Hello,

I configured one trunk between one Asterisk 1.8 server and one Cisco Unified 500.

The trunk works fine (for incoming and outgoing calls). BUT two minutes after the registration, the trunk become systematically UNREACHABLE on the Asterisk console.

I think my Asterisk server is correctly configured (other trunks work fine).

I thought that was a NAT problem. But if I test with a computer with X-Lite, everything works fine.

It could be a problem on the Cisco.
Anybody have any idea ?

Thanks!
