[OpenSER-Users] Aliases for outgoing calls
by mayamatakeshi 19 Jul '08

19 Jul '08

Hello, I'd like to permit our subscribers to have several aliases for outgoing calls (basically, several number in the PSTN). I think they could set this in the header From of the INVITE to us and we would identify them, authenticate them and finally relay that same alias (and not the subscriber name) to the GW (currently we permit them to have a single alias for outgoing using a field in the subscriber table). I can see the module alias_db can be used to manage aliases, but I understand it can only be used for incoming calls as it provides just a single function alias_db_lookup that operates on the Request-URI. Any ideas? regards, takeshi

[OpenSER-Users] avp_pushto
by Pablo Saro 18 Jul '08

18 Jul '08

Hi everyone, I have a doubt about the function avp_pushto(). When I do the following: ... avp_pushto("$ru", "$avp(s:devices)/g"); ... If $ru is an array with more than 1 position, avp_pushto works fine, but if both $ru and $avp(s:devices) have only 1 position, the function avp_pushto replace $ru with the new value. It cause loosing of the previous $ru. I believe that avp_pushto function shouldn't replace a value. Any idea? I'm using OpenSER 1.3.2 Thanks in advance. Pablo Saro psaro at google dot com

[Serusers] Forwarding calls to a ShoreTel System
by Freese, Bill 18 Jul '08

18 Jul '08

I will apologize in advance if this is the wrong forum or if this is an embarrassing newbie question. I am currently using an Trixbox/Asterisk system to connect a Rolm PBX to a ShoreTel phone system via SIP. The asterisk box doesn't correctly support the REFER method, so I'm hoping to use SER to proxy my SIP connections to allow the Rolm users to function correctly with transfers and conferencing. I have installed and configured my SER system using the getting started documentation. I have successfully interconnected my SER system with my Asterisk and with a Cisco 2801 and can place and route calls as I would expect. When I try to place a call through SER to my ShoreTel system, I get the standard "SIP/2.0 404 Not Found". If I compare captures of my successful SIP connection from my Asterisk environment to a capture of the SER attempt, the only real difference I see is that the INVITE TO: field has the IP of my SER system instead of the ShoreTel system. The actual INVITE uri is identifying the ShoreTel device, but the TO field has the SER address. The Asterisk connection has the address of the ShoreTel device in both places. I have tried to look through the docs and searched online, but I did not find any resources on this question. I would appreciate any feedback that could point me in the right direction. Here is a ser -V from my SER system version: ser 0.9.7-pre1 (i386/linux) flags: STATS: Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, F_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 @(#) $Id: main.c,v 1.197.2.1 2005/07/25 16:56:24 andrei Exp $ main.c compiled on 14:05:21 Jul 16 2008 with gcc 4.1.2 I route my calls to the ShoreTel system through the basic PSTN route from the getting started sample: route[5] { # ----------------------------------------------------------------- # PSTN Handler # ----------------------------------------------------------------- rewritehost("my.IP.addr.here"); # INSERT YOUR PSTN GATEWAY IP ADDRESS avp_write("i:45", "inv_timeout"); t_on_failure("1"); route(1); } Thank you for any feedback in advance.

[OpenSER-Users] openser and asterisk in the same pc
by Ricky Gutierrez 18 Jul '08

hi list , I am trying to connect openser with asterisk, but when I make calls to the pstn, it shows me a 407 Proxy Authentication Required , am trying to make groups of calls with openser that some extensions have permission of making calls to the pstn, others that alone they call internally and international. I have created 3 groups local, int, international, the extensions that are of the local group have permission I believe me, according to the theory to be able to make local calls,for this I am using asterisk, but this he throws me the message 407. The extension 112 with the address ip 192.168.10.26 belongs to the local group, and he makes an intent of calling to the pstn through asterisk, but this he throws me the message 407 I don't know because thank you for your help +0.399494 192.168.10.26:5060 -> 192.168.10.1:5060 INVITE sip:2642006@192.168.10.1;user=phone SIP/2.0 Via: SIP/2.0/UDP 192.168.10.26:5060;branch=z9hG4bKb7bfb742a0e47ab4 From: "Ventas" <sip:112@192.168.10.1;user=phone>;tag=ca46913c384c257c To: <sip:2642006@192.168.10.1;user=phone> Contact: <sip:112@192.168.10.26:5060;transport=udp;user=phone> Supported: replaces, timer, path Call-ID: fb973f9069a09ad7(a)192.168.10.26 CSeq: 59632 INVITE User-Agent: Grandstream GXP2000 1.1.5.15 Max-Forwards: 70 Allow: INVITE,ACK,CANCEL,BYE,NOTIFY,REFER,OPTIONS,INFO,SUBSCRIBE,UPDATE,PRACK,MESSAGE Content-Type: application/sdp Content-Length: 382 v=0 o=112 8000 8000 IN IP4 192.168.10.26 s=SIP Call c=IN IP4 192.168.10.26 t=0 0 m=audio 5004 RTP/AVP 0 18 3 2 99 9 4 101 a=sendrecv a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=rtpmap:3 GSM/8000 a=rtpmap:2 G726-32/8000 a=rtpmap:99 iLBC/8000 a=fmtp:99 mode=20 a=rtpmap:9 G722/16000 a=rtpmap:4 G723/8000 a=ptime:20 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-11 # U +0.000205 192.168.10.1:5060 -> 192.168.10.26:5060 SIP/2.0 407 Proxy Authentication Required Via: SIP/2.0/UDP 192.168.10.26:5060;branch=z9hG4bKb7bfb742a0e47ab4 From: "Ventas" <sip:112@192.168.10.1;user=phone>;tag=ca46913c384c257c To: <sip:2642006@192.168.10.1;user=phone>;tag=d7e793d797690be5ce5420203095040f.2cd4 Call-ID: fb973f9069a09ad7(a)192.168.10.26 CSeq: 59632 INVITE Proxy-Authenticate: Digest realm="192.168.10.1", nonce="48802341954eb0c26cd5eb2dd85f375325fb4a7d", qop="auth" Server: OpenSER (1.3.2-notls (i386/linux)) Content-Length: 0

[OpenSER-Users] How does Operser parse source port from request?
by KevinKinnan 18 Jul '08

18 Jul '08

I wonder that how openser parse the source port from the request. Does the parser function get the port from the header of packet(TCP/UDP) or from the content(by parsing Via header or something) of request message.

[OpenSER-Users] openser + mysql clusters
by Sajith T S 18 Jul '08

18 Jul '08

Hi! How is the overall experience like re. deploying openser with mysql clusters? Are there gotchas etc that need to be taken care of? (For example, a 2006 article [1] says that "The MySQL NDB engine currently runs its database completely in memory. This means that you have to be able to fit your database in memory." But this is not documented as a limitation in mysql faq.) Non clustered experiments were occasionally catastrophic, so can't risk taking that route again. Somebody suggested using drbd [2], but I did not quite like it -- it needs kernel modules, has more administrative overhead, is tied to linux, it is not clear how consistency (ie, state of in-memory data and on-disk data) is taken care of, and in any case ndbcluster appears to be the clustering solution with official stamp of approval. (Related - is postgres any better? Apparently postgres' clustering capabilities are "better", but then cdrtool etc seems to be written with mysql as the primary target.) Thanks, Sajith.
