SIP phones behind VPN no audio

Hi

a strage problem. I have a SIP phone behind 1812 configured for VPN to central office (PIX 7.2). This phone registers and can commincate with central office very neatly.

When this phone calls another SIP phone behind one more VPN (using 5505 or standard VPN client installed on PC) the call is established but NO AUDIO is heard by either phone.

Using SCCP works perfect.

The tunnel configurations are pretty standard. All ports open with proper inspections.

Can anyone help?

Thanks

Shruti

You should basically troubleshoot it as an IP issues. So first make sure you have ip routing working properly between points A and Z. After you can verify that, then make sure your firewalls are allowing RTP between those devices.
