Quote from: chilirock on August 07, 2017, 07:20:34 PMUpdate: I created a new support ticket with CallCentric when I found that the issue with the answering machine occurs with inbound calls to CallCentric, but not inbound calls to Google Voice. They had me send them the date/time stamps of a couple of calls where I had the issue. CallCentric support was able to review the call logs from their end and determine that the reason that I am hearing the beeps is that about 30 seconds into the call (e.g. after the Obi answers the call and after the answering machine plays the outgoing message) the Obi device sent a Re-INVITE packet back to CC to re-invite the call as a T.38 fax call. This explains why I'm hearing an intermittent beep tone on the line because the Obi is trying to establish a fax connection with the inbound call.So it looks like the theories presented here that the issue had nothing to do with the Obi device are not correct. The Obi is sending a re-INVITE packet back to CallCentric after the call has been answered. All calls I have tested are coming in from a standard mobile phone, not from a fax machine.The CallCentric support team was not able to determine why the re-INVITE message is being sent, they could just confirm that it was sent from the device. They sent me a couple of suggested configuration settings to see if it would resolve the problem. After making the suggested settings (see below), I no longer have the issue, even with the latest v5695EX firmware. The answering machine is working fine again.If anyone is interested in trying the settings to see if it resolves the issue with your answering machine, here they are. I only had to change a couple of these as a couple of them were already set the way they suggested. Based on the suggested settings, I'm guessing that the fax capability will no longer work. For me that's not an issue as I never use the line for faxes. But it may be an issue for others, so fair warning. ---Codec Profile A & B--- FAX Event Section- Enable: unchecked (mine was already unchecked)Codec Settings Section- T38Enable: Unchecked (mine was checked)- T38Redundancy: 0 (mine was set to 2)---ITSP Profile X (The Callcentric one eg. ITSP B)--- SIP Sub-section - X_SessionRefresh: Unchecked (mine was already unchecked)- X_FaxPassThroughSignal: None (mine was set to ReINVITE)What I still need to determine is "why" the Obi is sending the packet trying to re-establish the call as a fax. I will try creating a support ticket with Obihai to see if they can determine what might have changed in the recent firmware versions that is causing the issue. I'll post here again if I find anything new.
