[asterisk-users] Call problems

I have a DID from IPKall.com which is forwarded to my asterisk box.
Then this extension should call my ip phone using Dial application.
Everything works fine, except when I pickup the phone, I can talk, the other
party can hear me, but I cannot hear anything the person says on the ip
phone.
Then after a couple of seconds, the call hangs up.  I don't know why.

Here is the message I get:

 SIP/ipphone-09401f10 answered SIP/XX.XX.XXX.XX-09400918
    -- Native bridging SIP/XX.XX.XXX.XX-09400918 and SIP/ipphone-09401f10

I am running asterisk 1.6 on CentOS

Please help me fix this
