When using the UC520 inside the LAN voicemail works correctly. When trying to use outside such as to leave a message, it seems the voicemail picks up, but you cannot hear anything, the it disconnects.This is over a SIP trunk.


Anyone else had this? UC520 is running 8.0.2.


Thanks

Do you have:


voice service voip

allow-connections sip to sip


What codec is the SIP trunk using?

Try the following one at a time to see if either solves your problem.


voice service voip

no supplementary-service sip moved-temporarily

voice service voip

no supplementary-service sip refer


Hope this helps.

Thanks, but I already have that config in place.


Any other ideas?

Does "debug voip dialpeer" show the call coming in to the UC500 and hitting the proper dial peer? Could also run "debug ccsip messages" to see what the SIP messages say.

Hi Dan,


Any other ideas?



Might be a silly questions, but do you have transcoding enabled? You shouldn't need it if you are using the same Codec, but you need to be absolutely sure that the ITSP is indeed using the same Codec.


Also do you have the Codec type stipulated on the CUE dial-peer?


Was this system designed via CLI or CCA 2.2.4?


Also last but not least, have you checked your access list and made sure that the flow of traffic between the system and the ITSP is allowed?



Cheers,



David.
