I have a UC520 running an Auto attendant.
DDI is provided by skype.
When you call in on the DDI the AA plays the message, if you select option 1 it will ring an extension. All this works fine.
If the extension ring no answers to voicemail you hear silence?
any ideas

John,
My first thought was that the voicemail message was just blank. So, is there an actual message recorded, and can you access and hear it internally?
Since this is coming in over a SIP trunk, are you using G711ulaw as your codec, or is that the one being negociated? Do you have transcoding setup? I would try forcing the unit to use G711ulaw as a test, since this is the codec that CUE (AA and VM) uses.
Thank you,
Darren

hi Darren,
the messages are definetly note silence.
I configured the skype sip trunk with cca. I believe by default cca set the codec t 711u.
The system is a uc520, I havent configured transcoding.
How do I force the codec?

Hi John,
The system is a uc520, I havent configured transcoding.
I would strongly encourage you to configure transcoding on the system, and it could potentially solve this problem for you imediatly.
The only way I know how to do this in CCA is to enable conferencing capabilities, even if it is not used you still get the benefit of it and also the transcoding capabilities.
Is this a system completely configured via CCA or is this a Hybrid of CLI and CCA?
Cheers,
David.

Hi David,
I configured the box via CCA.
I tried to add conferencing but CCA prevented me due to lack of DSP resources.
Transcoding was configured (I guess by CA when the sip trunk was configured) I added a few more codec and made a test call again, Same issue, called AA option 1 which calls an extension, if the extension ring no answers, silence. Dont hear the greeting and no message.
I also set an option to call voicemail, when I do a test call to that silence also.

Hi John,
Two things for you to look at if you don't mind...
I am curious to see if all the DSP resources has been allocated to the SIP trunk, scary if that is the case because it means the UC runs out of resources too quickly and would require a larger PVDM or more of them.
You may need to consider contacting support and logging a case so they can do proper debugging, and just make sure that a PVDM hasnt dropped out into the ether, but the command above should show that anyway.
Cheers,
David.

Hi John,
It would seem that CCA has configured all available DSP resources to the SIP trunk... Whilst bizarre and a little odd I guess that is the way it is instructed to do it.
Assuming you have an SBS contract on this system, I would suggest having them investigate this issue and resolve it for you quickly, I can see what the problem is but any instructions provided would most likely take you out of support scope as it will require some CLI modification for testing purposes and may be too hard to explain on the forums.
Log a case, spend maybe a couple of hours with them and get it resolved it will be quicker than trying to work your way through it here.. Unless you do not have an SBS contract at which point we can talk about remote access to the system and do some further tests on it.
Cheers,
David.
