I have a problem with jabber clients. Jabber to Cisco IP phone and Jabber to Jabber calls work fine within our LAN.
The problem is when someone from outside the LAN trying to use Jabber over VPN connection we encountered these symptoms :
1- When the call is between 2 IPhone clients or an IPhone and cisco IP phone everything works just finee .
2- when one of the 2 call parties or both are android or pc ==> the call is successful " meaning: the caller can ring the receiver " but when the receiving party answer the call there's no voice and they can't hear each other
Appreciate your help
