Hello. I need to understand the source of my problem with SIP trunk and my voicemail server. I have a PBX that receive an SIP response 415 - Unsupported Media Type from voicemail server.
Here the conversation packets when I try to call to voicemail extension from an analog extension (thats need to be converted to SIP): PBX > VoiceMail | INVITE sip:[EMAIL PROTECTED],user=phone,transport=tcp; (default port 5060) VoiceMail > PBX | 100 Trying; VoiceMail > PBX | 302 Moved temporarily; (because the VoiceMail Server works with two processes) PBX > VoiceMail | ACK sip:[EMAIL PROTECTED],user=phone,transport=tcp; PBX > VoiceMail | INVITE sip:[EMAIL PROTECTED]:5065,user=phone,transport=tcp; (the port 5065 is for the second process, on VoiceMail Server). VoiceMail > PBX | 100 Trying; VoiceMail > PBX | 180 Ringing; VoiceMail > PBX | 200 OK; PBX > VoiceMail | ACK sip:<VoiceMail_FQDN>:5065,transport=tcp,maddr=<VoiceMail_IP_address>; PBX > VoiceMail | INVITE sip:<VoiceMail_FQDN>:5065,transport=tcp,maddr=<VoiceMail_IP_address>; VoiceMail > PBX | 100 Trying; VoiceMail > PBX | 415 Unsupported Media Type; PBX > VoiceMail | ACK sip:<VoiceMail_FQDN>:5065,transport=tcp,maddr=<VoiceMail_IP_address>; PBX > VoiceMail | BYE sip:<VoiceMail_FQDN>:5065,transport=tcp,maddr=<VoiceMail_IP_address>; Can anynone help me?
