Don't know if it's helpful, but 5580 is the integer representation of the IP address 0.0.21.204, so it looks like it is converting the dialed digits to an IP address somehow.

The plot thickens...

The packets are arriving at the remote gnugk but it is rejecting the incoming call. It seems that it is resolving the call to a mysterious IP address.

Here is the registration data from the console.

Number of Endpoints: 1

Why would the gnugk resolve 5580 to 5580@0.0.21.204 ???

..FG..
