Hello


Yes, look the routing rules (acl, firewall...) all that can to block the rtp.

The RTP and signaling protocol, use differente ports.

There is full routing between the 2 routers accross the WAN, there are also no firewalls in place or ACL's on any router interfaces.

is there anything else i should be looking at, or any other possible causes to this problem?

What is the codec utilized?

Try to create a voice class codec


Example:


(config)#voice class codec 1

(config-xx)#codec preference 1 g729r8

(config-xx)#codec preference 2 g729br8


On both routers and apply this voice class on dial-peer voip


example:


dial-peer voice x voip

voice-class codec 1


So, on dial-peer voip put the command:

incoming call .T


Example


dial-peer voice x voip

incoming call .T


Thx
