Hi! It is impossible to help you based on your un-detailed description. Much more information is needed: - does it happen also with other SIP clients? if yes, then you made a bad configuration with Openser and Asterisk, that means you are on the wrong mailing list - if "no", then what exactly is the outboundproxy doing? is it rewriting SDP? does it enforce a media relay? SIP traces would be useful too (e.g. on the outboundproxy execute: ngrep -W byline -q -P "" -t -d any port 5060) regards Klaus Am 11.02.2010 10:28, schrieb Jaguar Paw: > Hi, > My scenario is : > Registrar : Asterisk > Outbound Proxy : Openser > Registers successfully, Invite is done successfully but the voice is one > sided. > But if I do direct registering to Asterisk all things are perfectly fine. > In both cases i haven't use STUN. > Can anyone please tell me what is the thing i am missing? > Thanks > Paw > > > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org
