Hi Guys,

Long time no speak... I have an issue where I am not receiving in bound calls from SIP for Skype to my 201 Extension...

I have been on with the techs from Skype and they are seeing an internal error bing sent from the UC520:

SIP/2.0 500 Internal Server Error
Via: SIP/2.0/UDP;branch=z9hG4bK-14aed-4c334141-152d3a9b-b8f8d43
From: <sip:[email protected]>;tag=46b38d4e-13c4-4c334141-152d3a9b-3231e2f2
To: <sip:[email protected]>;tag=17AED8-605

However I can make outbound calls with no issue and my ddi number is displayed.

I have changed all variations on the inbound rule from +44 to 44 to 0044 to ext  201 and none seem to work.....

This has worked in the past with no issues ... I have changed nothing and all of a sudden it stops working....

Is my ghost back in my UC520 again?
