[Serusers] PSTN -> SER -> SEMS problem

[Alejandro Perez]

Hello.

	We have SEMS and SER working together ok for SIP to SIP calls. We also have
a Cisco AS5300 which connects via sip to SEMS through SER for PSTN
originated calls.

	When calls are made from SIP phones, the voicemail works perfectly well.
Now, when the call originates in in the PSTN and is routed to SEMS, we get
several errors (appended afterwards).

	I have also appended a copy of the invite produced by the AS5300 produced
by ngrep. I can see the "from" field is there???

	Any ideas of what may be going on??

Thanks in advance.
Alex
