[Sip-implementors] requirement to play media stream while on hold?
If you are placed on hold (a=sendonly), and the holder sends you a media stream, are you required to play it? I looked through RFC's 3261, 2327, and 3264, but I don't really see a requirement to actually play a media stream ever- when on hold or not. -- Paul Heitkemper Software Engineer [AI] 9701 Taylorsville Rd.

[Sip-implementors] sip trunking question
I hope this is apropos for this listserv. Is there a good source somewhere which describes (with examples) the messaging inherent in making a trunk? What does it mean to be a trunk? Thanks, Paul ___ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
[Sip-implementors] ***SPAM*** trunk information needed
I'm having trouble understanding how a trunk operates at the messaging level. Can someone please point me to some information that could help me? Thanks, Paul ___ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
[Sip-implementors] send audio to multicast address?
Can I send SDP to a phone to request it to send audio to a multicast Group, as opposed to the UAC in the Contact URL? Does anyone have any idea of how widely-implemented this is in the industry?
