Giqcass,
Thanks for the link. I have followed Mango's posts for years on DSLReports. I started with zero knowledge on this Obi feature and not sure I've progressed beyond zero. I had contacted Mango who is always kind and he gave me some help to get started. So I had the InboundCallRoute set to "telemarketers" and while knowing my digimap was brute force lacking concise language, it worked, for a couple months when only #'s were coming in.
Here are my updated observations; at girlfriends the other day, her phone rang for two or three minutes and she also had the "abc" in the phone's name field. Here are our similarities. Both using OBI, extended ringing occurs on GV line using SipSorcery, with IPComms DID, and not ringing other lines. I switched us back to this set up when it was announced OBI was dropping GV. If memory serves me, I had this issue years ago with the exact same set up (pre Obi days) and had the same issue on the GV line. My suspicion is that it may be IPComms testing the ports and why the extended ringing. My question is if these methods, Mango's #4 for example, (that I would have to figure out) will work seeing this is showing up in the name field not # field on the telephone and it may not be coming though a SIP provider phone system.
