My main phone is a Cisco SPA303 that I have configured to connect to my Anveo VoIP accounts. In order to use my fax machines, I set up an OBi202 to convert one of the Anveo lines to analog (fax machine). The Cisco phone is on a different LAN IP (obviously) from the OBi202. The OBi202 is configured for Line 1 out to an analog desk phone and Line 2 to my fax machine. All has been working fine until recently. I don't know why the Cisco phone will not receive inbound calls. All calls inbound ring the analog devices as if the digital phone doesn't exist. The Cisco phone will call out OK, just not receiving. I have checked and double checked the configuration pages for both devices including ensuring the passwords are correct. My Google fiber network map shows both devices and no issues. All that has changed recently is the LAN IPs and the PC operating system. Now that I have run into this trouble, I have fiddled around with the OBi202 configuration, but nothing I do changes the outcome.
