I am having trouble getting my DIDs to work with CBeyond. I get the error message: [CM010001] Line configuration does not allow identification of the source of this call. Check Advanced Options for Gateways and Providers and match a field to a correct value from the following: Contact IP: 'bwas1-vir.atl0.cbeyond.net'; From: '2817972464'; To: '2813787711'; Rline: '2813787711'; Contact: '' From the other posts I see others that have had similiar problems input the IP address for the contact field. But, I have a DNS name and the system will not take that. Any thoughts on what I should try? Thanks!
