I am looking for some help in regards to setting up the E61 to work off of my router, which is connected to my PBX. It is a IP-PBX config and I am attempting to set up the Nokia as an exstention. However there is one key problem that I can not seam to work around while the other wired SIP phones work fine on the system. (Note: friends SIP only WiFi phone is working perfect)

While the Nokia is showing that the registration has failed, the PBX is showing it as a live and active exstention. When wired phone dials Nokia exstention PBX send the appropriate request to the Nokia with no avail. The problem seams to be coming from ICMP and a port 3478 which appears to be assosiated with the STUN, and timing out issues of the Nokia (note: No firewall on system) Below is the captured packet data that I have added if anyone could help me make a little more out of this data.

Nokia appears to go to sleep after this portion and nolonger responds to request from system.

I may be a little over my head on this but any help anyone can offer would be great.
