In Line 439 of the attached log, you can see the REFER-TO
arriving at the Patton Smartnode 4960 gateway... the
REFER-TO is destined for mailto:'[email protected]'.
This results in the gateway trying to send the INVITE back
to the SipXecs server, instead of to the correct remote
destination (which in this case would be out an PRI line to
a Nortel legacy system).
If I do the same capture, but use the same handset, and dial
a call to '4495', the INVITE that arrives at the Patton
gateway destined for mailto:'[email protected]' (the number,
translated as per the dial plan, and the destination domain
as the IP address of the Patton). This is handled correctly
by the gateway, and the call routed correctly.
The root of the problem is, the SipXecs server, does not
evaluate/modify REFER-TO packets according to the same rules
that it evaluates initial INVITE packets, defined in the
dialplan.
I should also mention here, as I did in the ticket, that I
have updated the system from 4.2.1 to 4.4.0, and that the
behaviour still exists, and is consistent on both versions.
Cheers,
...Steve...
