Thank you by the interest, Iñaki. I don't know the answer to this new INVITE from PBX. In a normal operation, the RTP traffic should be initiated, right?
About the RFC, so, the server (voicemail in this case) do not send the list of acceptable codecs, unfortunately. Tha language (en-us), type (audio) and codec (G.711 uLaw) are supported for both sides. Can you help me to check this new INVITE? I have a .pcap file with this part of capture. Really thank you. > On Wed, Nov 26, 2008 at 1:59 AM, Iñaki Baz Castillo <[EMAIL PROTECTED]> wrote: >> El Miércoles, 26 de Noviembre de 2008, Fernando Mercês escribió: >>> Hello. >>> >>> I need to understand the source of my problem with SIP trunk and my >>> voicemail server.
