No sound Incoming Call [SIP]

[aproost]

I can call to my SIP-number but when I answer the call no I can't hear anything. When I call to the outside I can hear everything.

Config :
-IPOffice 500 (4.0.7)
-Telephone 5610SW IP

What am I doing wrong??

Check you have IP routes for the servers providing the RTP

Agreed with what Jamie says, though my guess is your IP routes are ok since you can make an outbound call.

Is your IPO behind a firewall? If so, what kind?

It sounds like you do not have the proper ports open. You need 5060 and all the RTP ports.

Also, depending on your firewall, the IPO can do the SIP Transformations, which means you should NOT do SIP Transformations on the firewall.
