[asterisk-users] Asterisk calls between 2 private networks

Did you set canreinvite=no in sip.conf on the phone in network B? A phone
that can connect but loses audio is almost a sure sign that it is
reinviting and your rtp packets are not making it to the phone. By turning
canreinvite off, it will keep asterisk in the middle of your sessions and
should give you the audio.

I'm using Digium Phones.
I still do not understand why it's not possible to do it the way the
networks are right now.
If the options I mentioned in my sip.conf are enough, then both phones
should use Asterisk as a proxy, and Asterisk should handle all the media.
I will run tcpdump traces tonight and will check it out.
My router has a bug and won't let me mirror port. From tech support I
need to reflash it. I'll do it and try it again.
