Re: One way Voice

Hi,

have you revised if there is any firewall between the endpoint and tht CUCM? If there is a firewall between them it's possibly that it is blocking some ports.

Re: One way Voice

You should check full ip path. How packed following. Ie in my case was similar problem.

My case was following :

             ISDN Pri                             h323

Cell GW --------------- Cisco GW(3725) ---------- Softswitch --- user

And between Cisco GW and Softswitch was router wich perfom nat for packets following to softswitch and I had problems.

In your case you should carefully check out connectivity and all network elements. Most often existing problem is firewall. Is it exists in your scheem ?
