[Serusers] Carrier-grade framework for SER
by Andreas Granig 27 Sep '06

27 Sep '06

Hi guys, I'd like to propose another possibility for a highly-available and scalable system design based on SER: The problems I've encountered for scalable systems are: - Distribution of the user location and alias location among the nodes (user location is based on registrations, alias location comes from web interfaces and is used for call forwarding). - Reloading up to date location tables after breakdown and recovery of a node So I'm just thinking loud about the following provisioning system: - Write a client which fulfills the this demands: - Receive one or more locations from SER via a SER module or from a web application and distribute them to other known clients. Take care of retransmissions if a client isn't reachable or reports a temporary failure. - Receive one or more locations from other clients and write them into the SER FIFO. If writing into the FIFO fails, try to write directly into the database (location-table, alias-table etc.). Report a temporary failure if this also fails. Maybe a centralized server should be used which receives the locations from the clients and distributes them to other clients, so that the nodes just know about the server and nothing about other nodes. This would make integration of new nodes easy. On the other hand, it's another single point of failure, so a decentralized solution should be considered. But that would mean that you've to inform every node about the existence of a new node. The protocol used between the nodes should be simple and fast. So I think SOAP drops out here. Maybe XMLRPC or ICE (http://www.zeroc.com/ice.html) could be used. One might think now why not just use replication on SIP layer, but t_replicate only supports one peer and you've no possibility to get locations on a node while it's down. Replication of other location tables like the alias-table is also not possible. I'd be willing to release these parts as GPL for creating an open framework for carrier-grade SER integration, so any feedback, improvements or flames are highly welcome. Cheers, Andy

[Serusers] Modifying "From" header field of an INVITE message
by scm-j＠nuntius.com 04 May '06

04 May '06

I am relatively new to SER. My SIP service provider requires me to present the ANI in the "From" field in my INVITE message header in E.164 format. I am currently sending this information as follows: From: "2125551212" <sip:2125551212@xxx.xxx.xxx.xxx> They want it in E.164 format as follows: From: "+12125551212" <sip:+12125551212@xxx.xxx.xxx.xxx> I see function only to modify the SIP URI but not the other header or SDP fields. Could someone help me with a code snippet that I can use in ser.cfg to do this conversion? Regards, SCM

[Serusers] Authenticate to Active Directory
by Bob McCormick 05 Dec '05

05 Dec '05

Does anyone know if there is a way to authenticate SER to MS Active Directory? I'd like to use an existing user database instead of having to manage users myself, and most of our users are in Active Directory. Has anyone tried this? What are most SER users using for authentication? Is anyone here tying into any kind of existing organization user database?

[Serusers] ser as outbound proxy only
by jeff kwong 26 Nov '05

26 Nov '05

Hi to everybody! Im currently trying to setup an outbound proxy using ser. Im still a newbie with this ser and im not yet that good with the scripting. Could anyone tell me how to configure ser for outbound proxy only using rtpproxy? There are samples files in the Getting started manual but im having troubles eliminating the authentication/mysql part in script since im not yet familiar which modules depends on which. A striped down version of the nat-rtpproxy.cfg file would be really appreciated. Thanks in advance. _jeff

[Serusers] failure_route question
by Java Rockx 25 Aug '05

25 Aug '05

Hi All. I'm using t_check_status() to do call forwarding on 486 Busy responses. I have an odd thing happening where SER receives the 486 Busy message (for which SER properly sends an ACK response) and then the failure_route calls append_branch() and t_relay() to try another destination. After the new leg of the call is setup and then torn down, the original 486 Busy seems to be hung in the tm module, because it magically appears in ngrep, which shows it being sent back to the caller as if the append_branch() never took place. Is there anything special that I should be doing to "swallow" the 486 Busy response to prevent it from being sent to the caller UA? Regards, Paul

[Serusers] LCR Module - Does it support PSTN prefix digits?
by Paul Hazlett 21 Aug '05

21 Aug '05

Hi All. We have multiple PSTN gateways in our network. Some are our own and some are owned and operated by 3rd parties. We are also use ser-0.9 stable with the LCR module for call routing. Some of these 3rd party PSTN gateways require us to prefix accounting digits to the R-URI before sending the call to their network. So my questions is this; does the LCR module support a scenerio whereby it can prefix digits for specific PSTN gateways? For example, suppose I have 3 PSTN gateways. The the second gateway requires prefixed digits on the R-URI. When the fist GW fails, the LCR module would prefix the required digits and then send to the send GW. If the second GW fails, then the LCR module would remove the previously prefixed digits and then send the call to the 3rd GW. Is this possible is the LCR module Juha provides for ser-0.9 stable? If not, is it possible with the LCR module in the unstable CVS HEAD? Regards, Paul

[Serusers] Replication problem
by Andreas Granig 19 Aug '05

19 Aug '05

Hi all, we use DNSSRV balancing and forward_tcp() to replicate registrations from one SER to the other SERs in the system. Now when one machine completely crashes, all other SER processes on all other machines hang when processing a REGISTER until tcp-connect times out, leading to a system load of ~16 per machine assuming 16 child processes per SER, and no other messages can be processed. I understand that replicating using UDP would solve this issue, but then replicated registrations get lost every now and then because of unreliable transmission, and as far as I found out t_replicate() can only be used for replicating to *one* other SER. This really gets me thinking about patching out the internal location cache and lookup every location from memory, because this additional lookup really doesn't hurt because of ~10 other DB queries per call. IMHO in systems with more than two SERs this cache is just a big pain. Andy

[Serusers] Setting tm module parameter "fr_inv_timer_avp" more than once during a call
by reticent 08 Aug '05

08 Aug '05

It seems that setting the "fr_inv_timer_avp" parameter more than once during a call is not possible. However there is a situation where this is necessary: 1. VoIP ATA to VoIP ATA call with call forwarding where call forwarded number is a PSTN destination To facilitate Call Forward No Answer, the fr_inv_timer_avp is used and set to a value (say 12 seconds), after this timer hits a failure_block is run, in this failure block i rewrite the destination and check if this destination is a PSTN number. If it is than I would like to change the fr_inv_timer_avp parameter to somthing higher due to the nature of PSTN termination but it does not seem to have any effect. Has anyone experienced this problem and possible found a workaround? Or maybe this is a known issue tavis

[Users] via header not added when transport=TCP?
by Erich Nahum 02 Aug '05

02 Aug '05

Howdy, I'm playing with OPENSER 0.9.5 with sipp as the workload generator on a bunch of linux boxes. When the transport is UDP, openser adds a via header like it is supposed to as a proxy. But when I use TCP no via header is added. This is a UAC->proxy->UAS scenario. Here's the header as seen at the UAS: | UDP message received [633] bytes : | | INVITE sip:service@10.0.1.41:5060 SIP/2.0 | Record-Route: <sip:10.0.1.42;ftag=1;lr=on> | Via: SIP/2.0/UDP 10.0.1.42;branch=z9hG4bKe9cc.cc24a79.0 | Via: SIP/2.0/UDP bronxville1:5060;received=10.0.1.40;branch=z9hG4bK-1-0 | From: sipp <sip:sipp@bronxville1:5060>;tag=1 | To: sut <sip:service@10.0.1.41:5060> | Call-ID: 1-31891@bronxville1 | CSeq: 1 INVITE | Contact: sip:sipp@bronxville1:5060 | Max-Forwards: 16 | Subject: Performance Test | Content-Type: application/sdp | Content-Length: 132 | P-hint: outbound And the corresponding message received at the UAS when using TCP: | TCP message received [495] bytes : | | INVITE sip:service@10.0.1.41:5060 SIP/2.0 | Via: SIP/2.0/TCP bronxville1:5060;branch=z9hG4bK-1-0 | From: sipp <sip:sipp@bronxville1:5060>;tag=1 | To: sut <sip:service@10.0.1.41:5060> | Call-ID: 1-31865@bronxville1 | CSeq: 1 INVITE | Contact: sip:sipp@bronxville1:5060 | Max-Forwards: 70 | Subject: Performance Test | Content-Type: application/sdp | Content-Length: 132 Note the absence of the 2nd Via header.

[Serusers] 1 way voice issue
by Sam Lee 01 Aug '05

01 Aug '05

Hi, I've recently encountered some problem with my SIP service whereby i call out to a specific number and i encounter a one way voice. If i'm the initiator, i cannot hear the other party but he can hear me. At first i thought it was a return route issue (as i'm going thru NAT) , so i switch my SIP to a public IP but i still face the same problem. Its really only that specific PSTN number that i have dialed facing this problem. The only difference that i can think of is that PSTN number is on a different route. I did a NGREP from my SIP server for the PSTN number that works (2-way voice) and the Number that doesn't work (1-way voice) . The only difference is there is an extra : NGW --> Proxy SIP/2.0 183 Session Progress..Via: SIP/2.0/UDP Proxy --> SIP Device SIP/2.0 183 Session Progress..Via: SIP/2.0/UDP for the PSTN number that works (the one with 2-way voice). Anyone has idea what does the Session Progress is for ? Or what problem am i facing ? Thanks a mILLION ! Regards, Sam

[Serusers] STUN for NAT traversal...
by Roger Lewau 01 Aug '05

01 Aug '05

I'm trying to use STUN for NAT traversal for all clients not using 1 to 1 NATing, and mediaproxy for the rare few who does.But it seems that all traffic is proxied anyway, dont really understand why. I do call the routeblock for mediaproxy before relaying the call, but since STUN is used it should not detect that NAT is in place. Or am I missing some logic? Any Idea on how to accomplish this? Kind regards Roger - Getting one step closer to a really god service everyday ;)

[Serusers] NAT Problem (Mediaproxy)... Pls help
by Yan Yu Lim 01 Aug '05

01 Aug '05

Hi Guys, I have a NAT problem, whereby I cannot get the RTP packets from a NATed user. Hence, I am trying to implement the Mediaproxy solution from ONSIP. 1. Mediaproxy and Ser are installed on the same PC, say 202.123.45.85. I've set SER to listen at 202.123.45.85, port 5060. How should I configure the ini file for Mediaproxy? Can someone please provide me with a simple example of how the mediaproxy ini file should be configured? 2. Assuming that I set mediaproxy to listen at 202.123.45.85, port 5061, & SER at 202.123.45.85, port 5060, how should my client's sip proxy setting be set? Is it 202.123.45.85:5061? 3. Mediaproxy has settings for proxy dispatcher & mediaproxy. What should be the settings for them in my case? 4. Do I need to configure additional files other than ser.cfg & mediaproxy.ini? 5. Lastly, for SER I am using : modparam("usrloc", "db_mode", 0) to check for all registered users online, do I use the command : serctl ul show Many thanks any suggestions. Regards, Zan

Thanks Ricardo - Do I need to add these to "versions" table in ser database? If yes, what is the version number for these tables?

[Serusers] Parrallel forking using SER and Mediaproxy
by Ramu Yadav 30 Jul '05

30 Jul '05

Hi all, I am experiencing some problems while configuring SER in order to fork between different contacts (a SIP UA and a SIP Gateway) and passing through a mediaproxy: The scenario is the following: (3 calls) UA1 -> SER : INVITE sip:ramu at xyz.com SER forks: SER -> UA2 : INVITE sip:ramu@[local-ip] {SDP is changed by mediaproxy module} SER -> GW: INVITE sip:PSTN-NUMBER@[gateway-ip] {SDP is changed by mediaproxy module} SER -> GW: INVITE sip:PSTN-NUMBER@[gateway-ip] {SDP is changed by mediaproxy module GW -> SER: 183 Session Progress SER -> UA1: 183 Session Progress {SDP is changed by mediaproxy module} Audio session with the mediaproxy is Active GW -> SER: 183 Session Progress SER -> UA1: 183 Session Progress {SDP is changed by mediaproxy module} Audio session with the mediaproxy is Active UA2 -> SER: 180 Ringing SER -> UA1: 180 Ringing UA2 -> SER: 200 OK SER -> UA1: 200 OK {SDP is changed by mediaproxy module} Audio session with the mediaproxy is Active. SER -> GW: CANCEL .... The call gets connected, but the problem is that the audio session is mute: onreply_route[1] { if (status=~"(183)|2[0-9][0-9]") { if (client_nat_test("1")) { fix_contact(); }; use_media_proxy(); }; }; Can you help me on this ? Thank you a lot in advance, -- Ramu Yadav

[Users] feature request
by Klaus Darilion 30 Jul '05

Hi! In many situations it would be useful to verify the destination IP address of a message before sending the message. E.g. I want to make sure that accounting and authentication was applied before sending a request to a gateway. loose_route and DNS resolving make it impossible to handle all scenarios in the config script. Thinking about the problem I got the following idea: The tm module should, after all DNS lookups, verify the dest. IP against a blacklist (e.g. the GW table from lcr module). If the dest. IP is on the blacklist, the message will only be sent if a certain flag is set. This flag will be set in the config script after all checks (acc, auth...) has been applied. What do you think about this idea? Any other ideas for this problem? regards, klaus
