VPN Tunnel is up but only Voice traffic is not passing.

Hi All,

We have a IP network setup with 3 locations Branch-A, Branch-B, Branch-C  (Branch-A 5510 Version 8.4(2), Branch-B ASA5510 Version 7.0(8), Branch-C 5505  Version 8.4(4)1).

All the tunnel is up between 3 locations and all the traffic are passing through the tunnel including the voice.

We are facing issue now that all the traffics are passing through the tunnel except Voice between Branch-A and Branch-C.

Attached is the running configuration and network diagram of all the locations.

Please help me out on this issue and thanks alot in advance for your support...

Hi,

There are multiple networks both on Site A and Site C. Can you tell us between which networks the traffic is not working?

Thanks for your Reply....

Branch-A: object group :  object-group network BDOQATAR_Network & object-group network BDOBAHRAIN_Network

Branch-C: object group :  object-group network BDOQATAR_Network & object-group network BDOBAHRAIN_Network

below these object group network-object 192.168.42.0 255.255.255.0  is a voice vlan of Branch-C and network-object 192.168.0.0 255.255.255.0 is a voice vlan of Branch-A. issue is that none of the any network can not communicate with Branch-C Voice vlan. rest everything is working fine. they can communicate each other.

Thanks in advance for your support

Hi,

You could try the basic "packet-tracer" test at both sites to confirm that the correct ASA configurations are hit.

Branch A

packet-tracer input inside tcp 192.168.0.100 12345 192.168.42.100 80

Branch C

packet-tracer input inside tcp 192.168.42.100 12345 192.168.0.100 80

The ports and IP addresses I chose randomly.

Please take the command on each unit twice and post the output of the second time you apply the command so we can see that the test matches the correct ASA configurations.
