Re: CUCM one side voice in Public network

As Ronak noted in your previous post, it will be an issue where the packet is not reaching the phones. I believe this could be a NAT issue or an ACL issue from the topology above. A ping test between the two networks will tell the tale. If the ping fails, you could start using traceroutes between the two networks to figure out where the packet is being dropped and rectify the problem.

One thing i tell you that its a routing problem. Also, i wouldnt have the same subnet (192.168.1.x) at two different sites, if this is actually your IP schema. I would suggest you open a TAC case to figure it out as this cannot be fixed over the forums, IMHO.
