check on the ACL setting at both sides. It can be something is blocking the voice traffic.

not all of the calls completed with dead silence, but some of them..

This situation is repeating frequently, can any one help me?

As a previous poster said, look for ACLs in the RTP path. This has always been the cause of a successful call setup with silence on our network.

Wich protocol are you using SIP or H323? you may investigate the codec negotiation between calling and called party.

Hi, i'm using h323, and the codec is g729r8 and i'm sure that both ends are using the same codec..

Thanks,
