[Serusers] incorrect Contact IP in contact header

[Iqbal]

Hi

I am using 2 xlite sessions of different PC's, and also a IP phone, now
the xlites when they register have the correct IP address in their
contact headers, basically they have the FQDN for my sip domain, however
the IP phone, it seems to be picking something else up.

The IP address in Call-ID for the xlites is the domain name, but in the
IP phone its a IP address of the phone itself, no probs there, but the
IP address shwn in the Contact header is 10.44.100.1...have no clue
where this is coming from, or where to force it to change...any ideas
