VoIP problems

Unanswered Question
Jun 1st, 2007


We have a E1 on Cisco3640 and router WAN Cisc3640 doing NAT. The VoIP in this scenario works fine, but after, we change the router WAN to Cisco 7604 but now we get voice in one-way. We're checking the E1 and there is not problem. What should we check?? Many thanks.

May be a difference due to some NAT behavior or bugs in different version. Without more details, is impossible to tell.
