Call Manager And PBX Integration

[anilkv]

I have a IP network in which I am running VOIP and IP telephone running.

Voip on this network is working.

For the integtation of PSTN with Iptelephone (CCM-V3.0(9)) I have configured the routers as H.323 Gateways and the H.323 gateways are registred on the CCM.

The Cisco IP telephones are able to place calls to the PSTN phones to remote location as well as noraml pstn extensions.

But at times when i dial the remote location number i am getting a cracking noise on the IP phone.

This happens after the full digits dialing.

When this noise happens, on the routers i am able to see the calls getting placed too.(Sh Voice Call Summary)

I changed with a new IP set and same problem continues.

Need help on this.
