[OpenSER-Users] Wrong R-uri in ACK
by Lucio Maciel 25 Mar '08

25 Mar '08

Hi... I'm getting some wrongs ruri's in the ACK for a final 200ok from an INVITE... It is comming as the original INVITE r-uri (number@host) and not the contact from the 200ok. There is something i can do to workaround this in openser? Thanks. -- ------------------------- - Lúcio Fernando Maciel - - lucio(a)tesatelecom.com - - Tesa Telecom - - R.

[OpenSER-Users] LCR... Too many entries
by Douglas Garstang 25 Mar '08

25 Mar '08

Ok, can someone please tell me why 4999 LCR entries is too many? What's the limit? Is it hard coded in the OpenSER source? Why?

[OpenSER-Users] uac_replace_from and CANCEL
by Andreas Granig 25 Mar '08

25 Mar '08

Hi, I hit another problem with a Cisco PGW in combination with CANCEL, and I'm not sure which fault it is. If I do uac_replace_from in the INVITE, the From-Header is altered somehow and sent to the PGW. So if A calls B where B is a PGW, the From from A to OpenSER is for example sip:a@somedomain and from OpenSER to B it's sip:other-a@somedomain. If the call is cancelled, the From-header isn't altered, so the From from A to OpenSER is sip:a@somedomain and from OpenSER to B it's sip:a@somedomain as well. Now the PGW seems to ignore this CANCEL, and I guess it's because of the different From-usernames, since it works if I don't do any uac_replace_from. RFC3261 says in §9.1: The Request-URI, Call-ID, To, the numeric part of CSeq, and From header fields in the CANCEL request MUST be identical to those in the request being cancelled, including tags. So is it correct behavior of the PGW because the From header in the CANCEL is different from the From header in the INVITE? Should OpenSER alter the From in the CANCEL as well? Or should the PGW just check the From tags, but not the From URI? Andreas

[OpenSER-Users] Adding header to self-generated reply (sl_send_reply)
by Alex Massover 25 Mar '08

25 Mar '08

Hello! I'm looking for a way to add custom header to self-generated replies. For example I have an $avp(s:test) and want to send 4xx with header Custom: $avp(s:test). Is it possible? I didn't find a way to add headers to sl_send_reply or t_replay. -- Best Regards, Alex Massover VoIP Development Manager Jajah Inc.

We can't have over 120,000 lcr entries??? Your joking? Why not? They're all in memory aren't they? Providers publish rate sheets with thousands and thousands of entries, and people often use multiple providers. I'm a little confused what LCR is even for then if it can't handle this. We need 6 entries in LCR because we have 6 OpenSER systems running. Each one needs to be configured differently, to send calls to different gateways. It's as simple as that. For example, our Hong Kong OpenSER needs to send calls to the Verizon gateway in Hong Kong, while our USA OpenSER needs to send calls to the Verizon gateway in the US. They don't all go to the same place. > >> Our providers also have sometimes have several gateways in a single >> POP.

Don't understand you. It just seems who ever wrote the LCR module really didn't think of the real world application.

[OpenSER-Users] v1.3.1 & bla
by Jeremy George 25 Mar '08

25 Mar '08

Hello All, I had bla working with v1.3.0, but it isn't with v1.3.1 . I didn't expect a maintenance release to require a configuration change, so I am confused. V1.3.1 appears to need a pua_bla server address statement in the modparams. I wasn't using one with v1.3.0, and it appears not to be allowed. The presence server configuration is very simple, just about straight from the example. It's attached as bla.cfg I think I have an idea about what's wrong, but not why. Attached also is are ngrep traces of the first and second UAs registering correctly with v1.3.0 and the first UA registering correctly with v1.3.1 . Then an ngrep trace of the second UA registering incorrectly with v1.3.1 . The NOTIFY that should be relayed from the second UA to the first is missing. The attached files are named firstphone-register-130.log, secondphone-register-130.log, firstphone-register-131.log and secondphone-register-131.log . Any pointers to the problem would be greatly appreciated. - Jeremy

Juha, Thanks. I went through that option yesterday. As we have 6 instances of OpenSER running, I would need to have SIX routes defined in the lcr table for a single prefix. For example (IP's modified): mysql> select * from lcr; +----+--------+---------------+--------+----------+ | id | prefix | from_uri | grp_id | priority | +----+--------+---------------+--------+----------+ | 8 | 1303 | @203.84.213.8 | 1 | 1 | | 9 | 1303 | @203.84.214.8 | 2 | 1 | | 10 | 1303 | @203.84.215.8 | 3 | 1 | | 11 | 1303 | @203.84.216.8 | 4 | 1 | | 12 | 1303 | @203.84.217.8 | 5 | 1 | | 14 | 1303 | @203.84.218.8 | 6 | 1 | +----+--------+---------------+--------+----------+ ..... All that .... six rows for a single prefix. Of course, we have thousands of routes for each of our providers... off the top of my head, we have about 17,000 routes between Teleglobe and Verizon... multiply that by 6 and you have almost 120,000 routes. Apart from the administrative hassle, can OpenSER handle 120,000+ routes in the lcr table ok? Our providers also have sometimes have several gateways in a single POP. However, we don't want to actually try and route calls to every single gateway in a POP, just a few of them. The LCR module doesn't seem to have a way to skip to the next lcr route. Can it do that? If it can't, we have to try every single gateway in a POP before skipping to the next carrier, which just isn't feesible.
