Cisco CallManager Express with Cisco Unity Express

Hello guys,

 

I have a question for you:

 

After configuring a Cisco CallManager Express with Cisco Unity Express, inbound calls from the PSTN SIP trunk receive a ring tone for 20 seconds and then a busy signal instead of voicemail. Which configuration fixes this problem?

SIP World, Unified Communications

Someone can help me?
thanks in advance

Marco

What if you call from internal extension, does that forward to VM ?

I would say it is most likely a configuration problem sending to the unity express module. We would need to see your configuration from the router and unity express module to take a look. Perhaps a debug ccsip messages when the call is made as well. 

Please rate if this helps.
