RE: [Serusers] Routing with ser / Problems with linphone

by Klaus Darilion

I just read the "ser status update" from jiri and he wrote in the "new features" section: - 3261-alignment: support for TCP and loose-routing So I think this will be fixed in the next release?

[Serusers] Routing with ser / Problems with linphone

by Klaus Darilion

Hello! I've installed ser (sip:obelix.ict.tuwien.ac.at) und want'ed to use it with linphone, so I configured linphone to use ser as outbound proxy and registrar. The registration works fine but not the INVITEs. ser answers to an INVITE from linphone with a 404 Not Found and I found out that the problem is the "Route" header in the INVITE from linphone. Route: <sip:obelix.ict.tuwien.ac.at;lr> When I remove the header from the invite and send it manually (sipsak) the ser proxy accepts the invite and forwards it. I think ser reacts wrong because if an RFC3261 proxy gets an request with a route header which points to itself it should remove the header and forward the request. Than I tried the same with an different proxy in the route header: Route: <sip:iptel.org;lr> Now, my ser proxy (sip:obelix.ict.tuwien.ac.at) accepts the request and forwards it to iptel.org, but it rewrites the invite to: INVITE sip:iptel.org;lr SIP/2.0 Thats what an RFC2543 proxy would do, but not an RFC3261 proxy, which only is allowed to do that if the route header has no "lr" parameter or if he is responsible for the domain in the request URI. If there is an "lr" parameter the proxy must not change the request URI. If I'm wrong please let me know. I use ser 0.8.10 with the standard config file and linphone 0.9.1 & 0.10.0 Regards, Klaus

FW: [Serusers] Initial setup on FreeBSD of ser using Cisco 7960 SIP

by Lenny Tropiano

Nils, Thanks! Setting listen=sip.voiping.com worked. I had listen=192.70.239.1 (which the reverse DNS records resolve to: voiping.com). So, that worked. Thanks for the help and the quick response. Regarding "not forking" it was purely for debugging purposes. It'll work now with fork=yes. Now I have: fork=yes log_stderr=no alias=voiping.com listen=sip.voiping.com Later, L. -----Original Message----- From: Nils Ohlmeier [mailto:nils@ohlmeier.de] Sent: Tuesday, February 04, 2003 1:57 PM To: Lenny Tropiano; serusers(a)lists.iptel.org Cc: 'VoIPing, LLC (IT Consulting)' Subject: Re: [Serusers] Initial setup on FreeBSD of ser using Cisco 7960 SIP Hi, On Tuesday 04 February 2003 19:09, Lenny Tropiano wrote: > I'm "playing" with SER trying to understand how it all works, and to > be completely honest I haven't finished reading all the docs. > Basically I'm using the default ser.cfg (installed in > /usr/local/etc/ser) and I have two 7960s with the latest SIP code.

Because from the repsonse packet bellow you can see that your request is going through end (nearly) endless loop. The via_cnt==12 means the request was forwarded 12 times (before it was stoped by the maxfws rule). I guess that ser cant detect that sip.voiping.com is one of its "myself" names. Maybe this is caused by the 'fork=no'. If not you can try to add 'listen=sip.voiping.com' to your configuration or the commandline switch '-l sip.voiping.com'. This should fix your problem.

[Serusers] Initial setup on FreeBSD of ser using Cisco 7960 SIP

by Lenny Tropiano

I'm "playing" with SER trying to understand how it all works, and to be completely honest I haven't finished reading all the docs. Basically I'm using the default ser.cfg (installed in /usr/local/etc/ser) and I have two 7960s with the latest SIP code. I know it works, since I can call the other phone with our user(a)iptel.org extension ... The 2nd line is setup to register to sip.voiping.com [192.70.239.1]. Immediately the phone gets to trying, I have ser running to "not fork, debug 3, and log to stderr". ngrep indicates the following: U 192.70.239.150:53087 -> 192.70.239.1:5060 REGISTER sip:sip.voiping.com SIP/2.0..Via: SIP/2.0/UDP 192.70.239.150:5060..From: sip:lenny@sip.voiping.com..To: sip:lenny@sip. voiping.com..Call-ID: 00036b54-b62d1fe8-314ef9d4-1cca7f7b@192.70.239.150..Date: Tue, 04 Feb 2003 18:07:32 GMT..CSeq: 101 REGIST ER..User-Agent: CSCO/4..Contact: <sip:lenny@192.70.239.150:5060>..Content-Length: 0..Expires: 3600.... # U 192.70.239.1:5060 -> 192.70.239.150:5060 SIP/2.0 483 Too Many Hops..Via: SIP/2.0/UDP 192.70.239.150:5060..From: sip:lenny@sip.voiping.com..To: sip:lenny@sip.voiping.com ;tag=e755c894a31056969aa313d5267cd575.f7b7..Call-ID: 00036b54-b62d1fe8-314ef9d4-1cca7f7b@192.70.239.150..CSeq: 101 REGISTER..Se rver: Sip EXpress router (0.8.10 (i386/freebsd))..Content-Length: 0..Warning: 392 192.70.239.1:5060 "Noisy feedback tells: pid= 71976 req_src_ip=192.70.239.1 in_uri=sip:sip.voiping.com out_uri=sip:sip.voiping.com via_cnt==12"....

[Serusers] New feature for the tm module [sticky proxy]

by Maxim Sobolev

Folks, We are currently trying to implement owerflow routing with sip and b2bua. Our network setup looks like the following (two GWs here is for simplicity, actually there would be dozens of them): --------- /--|PSTN GW|-\ ---- ----------------- ------- /~~~~~~\/ --------- \ /~~~~~~~~\ |UA|--|PROXY/REGISTRAR|--|B2BUA|--<IP CLOUD> <PSTN CLOUD> ---- ----------------- ------- \______/\ --------- / \________/ \--|PSTN GW|-/ --------- Since potentially each destination in the PSTN could be reached through more than one GW we would like to use that for adding some more robustness to the system, beause from time to time some of gateways might be unavailable for one reason of another (network outage, maintenance, overload etc.). t_on_negative() looks like a pretty suitable feature for the job modulo that we need to add some scheme for distinguishing real failures, such as "number is busy", from transient ones. The problem here is that b2bua is unable to do prefix-based routing, while we can't put b2bua between the UA and PROXY because for accounting reasons we should be able to get from b2bua IP number of the gateway the call was forwarded to. Therefore, we do gateway selection based on prefix in ser (using rewritehostport) and then just forward request to the b2bua using t_relay_to(). To catch failures and perform retries we use t_on_negative() and number of reply_route[] blocks and it is where the problem lies - after appending a new branch ser forwards the request to the host:port specified in the uri directly, but not through the b2bua. Attached patch adds a new variable sticky_relay_to, which if set to non-zero value instructs ser to record proxy address to which transaction was originally forwarded with t_relay_to(). On failure ser forwards request to that address if another branch was appended in reply_route[]. I think that it is generally useful feature and it would be nice to see it integrated into the next release. Thanks! -Maxim

[Serusers] (no subject)

by mko＠cs.stir.ac.uk

Hi, I have installed SER on linux and created a few users. I can register these users from SIP phones and soft-phones and can also establish connections between them. I have also created a user on the iptel.org server. I can ring from a client registered with my domain (cs.stir.ac.uk) the client registered with iptel.org. It works perfectly. However, ringing from the client registered with iptel.org a client registered locally doesn't work. Is this a config problem? How can I fix this? Any help is greatly appreciated!

[Serusers] Error message I don't understand

by s-ser-maillinglist＠hilft.net

Hello, I'm trying to use the presence agent that is in the CVS version. I added the module and the lines ---- if (method=="SUBSCRIBE") { subscribe("registrar"); break; }; ---- to my ser.cfg file. By changing this I get the following error message when trying to "sign in" with the msn messenger UA: ---- 15(23129) ERROR: t_reply: cannot send a t_reply to a message for which no T-state has been established 15(23129) send_reply(): Error while sending 200 OK ---- What does this mean? I admit I don't know a lot about the details of the SIP protocol, but if you'd give me a hint on where to search, it'd help me a lot. Is the presence agent in CVS already usable at all? If yes, could someone please provide me a working config file? Thanks in advance, Stefan Schmidt

[Serusers] Windows Messenger authentication fails.
