I think you should narrow down your question to specific components and ask the question how to achive each component using the different modules to pjproject exposes. IMO the following components are a must in a workable PBX framework. You might get a better answer if you will be more specific. 1. Registrar - (Yes) 2. SIP Proxy router (or B2BUA) - (Yes) 3. Media Server (Auto-attendant, MoH, Voicemail) - (Yes) but i've seen post in this list that pjmedia is not wired and therefore would not perform well in a multi-channel environmnet 4. SIP Trunk compatibility layer (ISTP interoperability) - (Yes) 5. RTP Proxy for NAT traversal - (Yes) 6. Payload Transcoders - (Yes) 7. Device provisioning - (No) 8. ISDN interface (if you plan to support POTS in the PBX) - (No) Joegen On Saturday, 11 September, 2010 02:58 PM, Jonas Gauffin wrote: > Hello, > > Is the pjsip stack suitable to create a pbx? > If so, which layer do you recommend me to use? > > Regards, > Jonas > > > _______________________________________________ > 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 > -------------- next part -------------- An HTML attachment was scrubbed...
