Nothing audible with outgoing calls - Obi100 with Simonics GVGW

(1/9) > >>

precht:
Everything was by and large working well since switching over to the GVGW a few days ago, after preventing the SIP scanners.

Unfortunately, noticed starting this afternoon that neither of my Obi100 devices are able to make outgoing calls -- the destination number answers, but there's no audio on either end. Some incoming calls also just ringing, but similarly, when I answer, nothing's audible on either end.

I've tried reverting all the default/factory settings and rebooting, including reverting under the Expert configuration menu, re-added GVGW and it shows as registered under SP1. All using SteveInWA's helpful GVGW settings, including port 5060, from https://www.obitalk.com/forum/index.php?topic=13147.0

Also played around at the Simonics GVGW portal page, setting Google Voice to "Offline" and back "Online", but no improvement. Google Voice seems fine, as I can make calls using the Hangouts app and via the desktop Hangouts site.

Very peculiar behavior, and would appreciate any tips.

One-way or no-audio symptoms like this are usually due to NAT problems or SIP ALG interfering. Check that you don't have a SIP ALG or SIP Helper turned on on your router.

Thanks for the prompt response. I Google'd and notice my Netgear router does have a "Disable SIP ALG" option (https://kb.netgear.com/30796/How-to-disable-SIP-ALG-on-your-NETGEAR-device-using-the-genie-interface), so I enabled that setting and rebooted the router, but no improvement, alas.

Everything was working well for a few days, and I hadn't changed any of my router (or Obitalk) settings, so it's a bit befuddling.

For reference, I'm attaching screenshots of my System Status, ITSP SIP A and SP1 options from my Expert configuration settings.

Playing around with several phones and teased things out a bit -- this inability to call (and sometimes receive) appears to only affect my GV numbers on the Obi. I've tried incoming and outgoing calls with numbers on Verizon and AT&T and they were fine with my Obi/GV. It seems to only affect calls between GV numbers involving the Obi, oddly.

On a family member's line, GV is forwarded to the device and wouldn't work for any incoming/outgoing calls from either of our Obi devices -- but if we bypassed the GV number to her direct number, both incoming and outgoing calls were fine from my Obi/GV.

So to summarize...
Not working:
-GV (Hangouts) to GV (Obi/GVGW)
-GV (Obi/GVGW) to GV (Hangouts)
-GV (Obi/GVGW) to GV (Obi/GVGW)

Working:
-Non-GV to GV (Obi/GVGW)
-GV (Obi/GVGW) to non-GV
-GV (Hangouts) to GV (Hangouts) -- separate devices calling with Hangouts, e.g. mobile and desktop

SteveInWA:
I can't tell from your posts which OBi devices you are using with GVGW vs. Google Voice directly.  However, you should understand that this is an "all or nothing" scenario:  you must either only use GVGW or only use the native Google Voice support in current OBi products, not a combination of both.
