[Serusers] media and RTP -proxy
by Andrey Kouprianov 10 May '06

10 May '06

Guys, hi! Where can I download mediaproxy and RTPProxy tar balls??? I see that RTPPRoxy download from Portaone's site was discontinued? And I did not find a single link for mediaproxy either (though it should be downloadable from iptel.org, is that right?) Eagerly waiting for your reply. Anyone's reply.... Andrey.

[Users] ACK is sent before the re-INVITE to OpenSER, but the proxy relays the re-INVITE first (call flow in the body).
by Alexandre Abreu 10 May '06

10 May '06

Hello. Below it's the call flow. UAC CALL CONTROL 1 OPENSER 1 GW | | | | | INVITE F1 | | | |--------------->| | | | 100 F2 | | | |<---------------| INVITE F3 | | | |--------------->| | | | 100 F4 | | | |<---------------| INVITE F5 | | | |--------------->| | | | 183 F6 | | | 183 F7 |<---------------| | 183 F8 |<---------------| | |<---------------| | | | | Early Media | | |<==============>|<===============|================| | | | 200 F9 | | | 200 F10 |<---------------| | |<---------------| | | | | | | | ACK F13 | | | |--------------->| | | | re-INVITE F14 | | | |--------------->| | | | | re-INVITE F15 | | | |--------------->| | | | ACK F16 | | | |--------------->| | | | | | | | 500 F17 | | | | <--------------| | | | | The problem is between F13 and F16. Why OPENSER relays the re-INVITE first (F15), if the ACK (F13) was sent before and arrives before? And I am sure that this ACK hits a t_relay(), because after the re-INVITE sent, the ACK (F16) is sent normally... I am using OpenSER 1.0.1. Any help is appreciated. Alexandre

[Users] Information to learn OpenSER and SIP
by Manuel Ángel Rubio Jiménez 10 May '06

10 May '06

Hi, i'd like learn more about SIP and OpenSER, but i don't found information about OpenSER with MediaProxy, how works OpenSER with RADIUS (by example) and other things. I don't like HOW-TO, i don't need know how to install anything, i need understand how works each component (openser, radius, mediaproxy...) and some about SIP and RTP. Regards. -- Manuel A.

Can someone post/link to some examples of how to use avp module to write/read data to/from MySQL tables? The openser.org docs are reeeeealy bad. Doug.

[Users] more outbound proxies/openser & one register/*
by Peter Hudec 10 May '06

10 May '06

hi all, I haven't found so far any suitable solution for my problem. I want to have more outbound proxies and only one register. Outbound proxies should be also RTP proxy for clients /for all, or only behind NAT, it doesn't matter/ My idea is, that the REGISTER server see the IP of the outbound proxy, not the UA it self. Insipired by siporxd and milkfish project I wrote a patch for nathelper to rewrite the contacnat addres to IP of the proxy. If the proxy receives REGISTER, it save the contact and send new to to register with it IP. The signalinig is working good. But I have problem with RTP streams and the SDP part of the INVITE request. If you try to call between two proxies, the RTP goes PROXY1<->REGISTER<->PROXY2, instead of only between PROXY1<->PROXY2. Also if you made a call between 2 phone on the same proxy, the call passes through REGISTER ;( The example openser/nathelper configuration is working good, if the proxy is also register ;) I have atteached my own. Can anyone just a bit help me with configuration or give me a link to the another sip proxy project, which can satisfy my needs ? best regards Peter Hudec -- Things are easier than they appear; all you need is the right focus Leonardo Balliache # # $Id: nathelper.cfg,v 1.1.2.1 2003/11/24 14:47:18 janakj Exp $ # # simple quick-start config script including nathelper support # This default script includes nathelper support.

[Users] Problem with RPID
by Bogomolov Andrei 10 May '06

10 May '06

I use radius authorize reply to set AVP rpid value: 0(30405) DEBUG:auth_radius:radius_authorize_sterman: Success 0(30405) DEBUG:auth_radius:generate_avps: getting SIP AVPs from avpair 225 0(30405) DEBUG:auth_radius:extract_avp: string is <rpid:9284444> 0(30405) DEBUG:auth_radius:extract_avp: AVP name is <rpid> 0(30405) DEBUG:auth_radius:extract_avp: AVP val is <9284444> 0(30405) DEBUG:auth_radius:generate_avps: AVP 'rpid'/0='9284444'/0 has been added But when this caller is invating, openser writes to log: 0(30405) append_rpid_hf: No rpid AVP The question is: where are SIP-AVPs stored? Do I have to load auth_db in openser.cfg? Or avps could be stored in RAM without mysql database?

[Users] asterisk and openser - CallerID
by Paul Cupis 10 May '06

10 May '06

Hi all, I'm having some trouble integrating openser with asterisk. I am able to make/receive calls PSTN<>asterisk<>OpenSER<>SIP-client fine, and the SIP client received the PSTN callers CallerID, but I cannot get the SIP-originated call to present a useful CLI to the PSTN recipient. FWIW, I have been able to set the CallerID manually from AGI scripts and the like, and it works from IAX<>asterisk<>PSTN. In openser.cfg I have: # Append Remote-Party-ID header field xlog( "L_INFO", "appending rpid" ); append_rpid_hf("", ";party=calling;id-type=subscriber;screen=no"); and I can see the RPID header in the SIP traffic. In sip.conf I have: [openser] type=friend context=from-openser host=<hidden> insecure=very trustrpid=yes amaflags=billing We are using asterisk 1.0.7 atm and openser 1.0.1 with MySQL backend. I've tried setting the rpid field in openser.subscriber to various settings but it is not making it to the PSTN recipient. Any ideas/gotchas with this sort of setup, or any further information required?
