VOIP over VPN Issue :(

[taufeeq taufeeq]

Hi,

We have a branch office connected to Head Office Via VPN. Both ends have Public IP. Call Manager, Unity Express, Voice Gateway are @ HO.

The IP Phones can register automatically but the problem is that Only HO can hear to the voice of the users from branch office and they cannot hear to HO users.

Disabled sip inspection and tried but no profit.

Please somebody help me on this.

Regards,

Taufeeq.

Hi

Probably a routing issue. Capture the RTP stream at both ends and check where it fails. Assuming you use SIP, you can check the audio address and port in the SDP messages of both the INVITE and OK, and veify that both addresses are reachable from the other side.
