Why does this call fail?

[seanwg]

Hi,

I have a Nokia E65 using Brekeke Sip Server as a proxy server; another terminal registered off the Brekeke server is a Sipura 3000.

I can succesfully call from the Sipura to the E65, but when I attempt to call the Sipura from the E65 the call fails upon the Sipura going off hook - The E65 displays on the screen "Internet Teelephone service not available" as soon as it receives the OK from the Sipura via the proxy. Any idea?


This is the OK message which the SIPURA sends to the E65 before I get the above error message:
