I can see you've tried calling route[NATMANAGE] just before the route[TOVOICEMAIL] ! and that didn't work. Can you paste your configuration as well as a SIP trace for a voicemail call ! some logs of the same calls will help too.

Greetings,

Here's another problem I'm having with kamailio 3.2 and the standard
kamailio.cfg script.

If the calling device is NATed, everything works fine if the original
call gets connected. That is, the INVITE sent to the called device has
the correct NAT fixups applied.

But if the called device fails to answer and the script runs
route[TOVOICEMAIL], the call connects, but the INVITE sent to the
voicemail server doesn't have the NAT fixup applied. The result is
that the audio is connected in only one direction.

It would appear that some rtpproxy function needs to get called to
apply the fixups prior to sending the INVITE to the voicemail server.
I've tried adding calls to route(NATMANAGE) at various places, but to
no avail.

Any ideas?
