I am trying to get a UC520 to receive incoming calls with an ITSP.
Outbound works fine.
Per the carrier he states a 500 Internal Server Error. I have upload his info.
Per other posts, I have read about fixing access-list 2 and the ip address that the calls are coming from.
I have addedd the two extra ip's and still no inbound calls.
Any suggestions. I have upload the info from the carrier.
Any other thoughts.
