[Serusers] SEMS IVR

[Joao Sampaio]

Hello,

I'm trying to work with the IVR from SEMS.
I've looked to the example config file that is in the CVS and I realised
that is very similiar to the one that I have to Voicemail.
So, I just wrote other condition "If" in my Voicemail script so that SEMS
answers with IVR from requests to sip:ivr at domain

What is happening is that SEMS answer the call but them imediatly send a BYE
message and the call is terminated without no answer.

Does anybody had the some problem?

Here is is my Voicemail and Sems config file

Thanks.

Best regards,

João
