[asterisk-users] Everyone is busy/congested: IP Trunk

[bilal ghayyad]

Hi Friends;

Actually I would appreciate if Vivek can advise if the
VPN resolved the RTP packets in the SIP Trunk between
Asterisk and another softswitch? In other words,
openvpn helpful in NAT cases in what exactly? As
without VPN, I was able to establish a call but
without voice or with complete noise (nothing
understood) :) - So if NAT resolve this issue for the
SIP Trunk, then I can proceed forward, as really now I
do not have any other attempt to try.
