Skype for SIP Configuration

[jaydien1358]

Hello,

I've been trying to get this Skype for SIP trunk configured but have had no success. Can't make or recieve calls although the SIP trunk is showing as registered.

Debug ccsip messages shows the following output. I highlighted some errors messages that are obvious. Can anyone help me?

I applied the change via CLI and inbound calls to the SIP are still working as they should. Also, MWI is still working as well (Although it was working with the quick fix before also).

Thank you for your prompt attention to my issue. Much appreciated.

Hi Guys,

I have the Skype for Sip working well receiving and making calls...

However when the voicemail is supposed to kick in I receive a message saying "There is no mailbox associated with this extension" which is not the case.

When I call the extension from another one it drops into vmail as it should...

Can someone help?

Thanks

Brian

Does your Voicemail extention start with the same digit as your SIP trunk DID?

Hi Brian,

No it doesnt, I have left the voicemail number as 399 but I have a skype in number assigned to the Skyp for SIP (+44 131 208 5555) and my skype tunk is 9909905**********

Have I done something wrong?

[jaydien1358]

Not quite sure as I am a novice as it pertains to troubleshooting SIP trunks.

I thought your issue might have been related to my orginal issue in this post where my SIP trunk DID started with the same digit as my PSTN access code which caused a conflict.

But I have yet to test inbound calls over my Skype SIP trunk when the call is transfered to VM. Let me see if I can replicate on my system.

What IOS are you running?  Is that call being forwarded from anywhere to get to your UC500?  Can you perform a debug ccsip messages?  If you don't want o post the result here, PM me.

Ted Trentler reported something similar that I was not able to reproduce on my Skype for SIP here.

Here is what he stated (all comments are on the Skype for SIP guide at https://www.myciscocommunity.com/docs/DOC-10787

My new issue is this.  When A call is redirected to voicemail from an IPphone Skype DID starting with 9905........... the number translation does not work properly.  Unity Express says that there is no number for that extension.

To get a Skype call to successfully redirect to voicemail I went to the web GUI of Unity Express (by default its http://10.1.10.1 from a PC local to the UC500 LAN) and had to define an E.164 number for the user.  The E.164 number that worked was the 9905.......... number
