    I'd appreciate anyone's advice on an issue I'm having. I've followed the instructions from the article "Creating an OBi200 Google Voice Trunk to Use with Asterisk" and I have no audio either way. The trunk is showing online in IncrediblePBX GUI and calls do seem to ring both ways, inbound/outbound using my cell phone, but there is just no audio and then after 30 seconds asterisk drops the call with this error:
    [2018-05-28 15:50:19] NOTICE[29313]: chan_sip.c:29574 check_rtp_timeout: Disconnecting call 'SIP/obi200-00000018' for lack of RTP activity in 31 seconds.

    I'm running Incredible PBX 13.0.192.19 on a raspberry pi, use an Obi200 with firmware 3.2.2 (Build: 5859EX). The obi200 and incrediblepbx are on the same network, same switch.

    You might confirm that your Obi200 is not rebooting. I followed the same article and am getting the same lack of RTP activity message in the Asterisk logs. However, I determined that it was caused because the Obi200 is actually rebooting. I am going to try a different version of firmware to see if that helps...

    I'm having the same problem.. I've carefully configured the Obi per Ward's instructions and am able to make/receive GV calls but without audio in either direction and the calls drop shortly after being answered.

    I can also confirm that my Obi is rebooting as evidenced by the Obi up time status after the failed call is a small number.

    I'm using the latest Obi firmware.

    In casting a wider net for answers I see someone brought up the issue on the Google Voice Help Forum.

    They had first opened a ticket with Obihai and were told by tech support that the Obi is incapable of bridging a Google Voice connection to a sip trunk.

    A forum member "Bluescat" was happy to jump in and obfuscate without confirming what Obihai tech support has claimed.

    I found the exchange on that forum hilarious but not helpful.

    I'll be looking for progress on this issue here because it seems the Google Voice Help Form is helpless....

    There is a couple of links that provide instructions that apparently work, although I myself have not yet tried it:

    https://www.dslreports.com/forum/r31954649-
    https://www.obitalk.com/forum/index.php?topic=10626.msg69940#msg69940

    Then a much older post just for research: https://web.archive.org/web/20150305102711/http://tech.iprock.com/?p=6416

    I look forward to trying these over the next few days as time permits and will report back here.

    Thanks!!

    Rather than starting with the dslreports post, which was put together rather fast and contains at least one error, you'd probably be better off following the more detailed instructions published here:

    Many thanks! I haven't yet tried the instructions in the previous post.
    I'll start with the one you suggested and will report back soon.

    I'm sorry to report that the instructions provided in https://cboh.org/voip/obi/OBi_As_ITSP.html are yielding the same results as other configurations such as the one outlined on NerdVittles.

    In all configurations I've tried I can initiate and receive Google Voice calls but there is no audio in either direction and the calls drop shortly after being answered.
    In all configurations the Obi200 crashes and on rebooting the uptime has gone to zero.

    Which configuration do you have and which method did you try? What firmware do you have loaded on your OBi? What does the OBi Status page indicate (Registered, Reg not reqd, or something else)? Do you have the opus codec loaded? Can you make a successful call on your GV line directly from the OBi? We need more information.

    In my case, calls from a standard phone attached to the Obi200 using the google voice set up on sp1 outbound work just fine.

    I am having a similar issue (using the latest stock wazo), but I can receive calls and the sound quality is fine. My issue is that I cannot make outbound calls after following Ward's tutorial. I just get a fast busy signal and the call fails. I have the latest firmware in the Obi200. I do not have the opus codec loaded (only codecs loaded are G.711 u-law and a-law). I can make a successful call from the GV line with a phone directly connected to the Obi. The SP1 (GV) status shows "connected". It had shown "registration not required" before, not sure why it's changed. I could not make or receive calls through the PBX with Ward's setting of Voice Services > SP3 > URI: user@ip.address. If I changed it to just ip address I could receive calls.

    In the Obi device status, for SP3 service status I keep getting the error: Register Failed: 404 Not found (server=my.ip.add.ress:5060)

    In my Asterisk logs I get NOTICE[2634] chan_sip.c: -- Registration for 'my_GV_SP3_user_password@local.obi.device.ip' timed out, trying again

    I really need to get this working asap, if there is any other information needed please let me know.
