can't hear voice from 7960 (CCM 3.2.2c)

I have such problem ..

i try to call somewhere to PSTN from my cisco IP Phone 7960

connection established .. and i can speak and hear other side ..

next moment i drop the line .. and redial this number again

and i see .. "connected" status on my IP phone but can't hear other side

and other side also can't hear me again ..

next few times i 'm trying call this number again and .. sometimes can hear otherside .. sometimes not ..

we use CCM 3.2.2c with hotfix F and cisco 5300 gateways

problem dos't depend if i use NAT or use real IP addres onmy ciscophone

You may have to Bind the H.323 Signaling to a Specific IP Address on Cisco IOS Gateway / Routers.
