I've added a third SIP Provider / Account to my UC320W. However inbound DID calls (only with the new provider) are proving to be challenging to get thru to the 320. Some ring, some disconnect, some come trhu as a fast busy. When I configure a softphone for the new provider everything rings thru as it should.
The provider is indicating that its equipment on my side appears to be the problem so I'd like to either confirm this or better understand what the logs indicate so that I can go back to them.
