I'm dealing with an issue where inbound calls that are first answered on our CS1000 and subsequently transferred to voicemail experience no audio when the call hits voicemail. To summarize, this is being caused by the CS1000 sending an INVITE back to the ITSP as it's transferring the call to voicemail. This is causing the ITSP to default to G.729 since no codec negotiation is being done at that time, and we only have support for G.711.
I found this Technet post regarding the same issue but between a CS1000 and Lync server.
Does anyone know of a way to always have SDP messages present in SIP packets sent by the CS1000?
