I just posted this previous question in the wrong forum. This is a repost..my apologies
Here is the problem I am experiencing.
I have two locations, each with multiple subnets.
Each of these locations has a vlan for IP phones and a vlan for the Cisco Call Manager.
The lan to lan tunnel with an Asa5520 and an asa5505 comes up and works fine. I can ping from any subnet to any subnet just fine.
However, the voice traffic has problems.
The call managers will set up the traffic and ring the end stations but there will be no audio.
For troubleshooting purposes, I have moved some phones into the vlans where the call managers sit and these phones have no problem placing phone calls. There are NO audio problems whatsoever.
I can then do an extended ping from one end of the network to the other using the phone vlan interfaces on the layer 3 switch and after that I am able to succesfully place calls
It's just when the phones sit in a different vlan than the call manager that these problems occur...unless I perform the extended ping.
Making it worse is that the existing ip structure has 172.17 and 172.27 addressing on both sides of the network making supernetting difficult.
I have tried different code levels and this does not seem to make a difference.
TAS has said the config looks ok so I am left scratching my head.
Has anyone seen anything like this ?
