In our situation, it only happens on phones that have been upgraded to 1.0.9.*** (all minor versions).
No issues on any phones running 1.0.7 or 1.0.8. We’ve had phones with the issue running 1.0.9, and once we downgrade them the issue goes away.
The weird part is that as a temporary fix, I installed 8 new phones that shipped from the factory running 220.127.116.11, and none of them have had any issues. I’m not sure if something with the upgrade process is going wonky, but definitely something weird.
.x is not telling me which version as there was 102, 108, 121, 127 and 132. 108 was removed from circulation as it had an issue with codec negotiation. Most of the reports I have see have involved the 12X versions, but as AFAIK, those that upgraded to .132 have not reported it since. While I cannot say that this is a definite fix, I can only say the absence of any reports is promising.
The only “bugfix” I see in the .132 release notes are below, and I can’t say that anything quite matches the reported problems (that we are sharing here on a single GXP2140 device). Anyone?
• Fixed No audio issue with call pickup answering
• Fixed One-way audio issue after picking up monitored BLF call if caller is using certain audio codecs
• Fixed No audio issue after RE-INVITE
• Fixed Device does not send PRACK in ALLOW header when sending 180 Ringing
• Fixed Phone replies with 200OK “sendrecv” upon receiving INVITE “sendonly” for SIP/UDP and
SIP/TLS with Broadsoft
• Fixed Phone displays N/A on screen if weather service is unavailable
• Fixed Broadsoft UC-One: Not reusing authorization header for XSI
• Fixed Broadsoft UC-One: Dialing conference with ID and PIN have DTMF issue for IM&P
• Fixed Security vulnerability issues
I agree, nothing mentioned that indicates the issue or a fix. I can only indicate what my experience was as well as others.
I assume that just as they may unknowingly break something with a new version, they may also unknowingly fix something as well. I also assume that the possibility exists that not every problem or fix may be reported.
Updating this phone to the 18.104.22.168 on this phone has not cured the problem for my client. Calls continue to come in that they cannot answer.
I managed to locate a copy of 22.214.171.124 for the GXP2140 device. I don’t know if putting that in will help at all or make things worse.
I have copies of firmware for 126.96.36.199, 188.8.131.52, and 184.108.40.206 if you want them. Not sure they’ll help but, I’ve got 'em if you want 'em.
The firmware.grandstream.com website doesn’t link to them any more, but .zip files with previous versions are still available for download:
220.127.116.11 18.104.22.168 22.214.171.124 10.0.8.56
I don’t actually have a full list of what versions were released, so can’t say if there are any earlier or later without attempting to download it manually. I am unable to pull down the .36 or .44 versions you mention.
I think that if firmware were the issue and as you have experienced it on numerous versions, there would hundreds if not thousands complaining.
I suggest you do a capture of a call if possible.
BTW, are you the same as mkras who posted earlier?
I can’t do packet captures, I’m working remotely from an entirely different subnet/lan.
The office is a new installation, with a hosted freepbx 14. All the other phones are GXP2130 with 126.96.36.199 and not experiencing this issue. The receptionist has a GXP2140 with some sidepanel extension boards, and this is the single phone that is intermittently unable to answer calls. Call comes in, everything on the phone is blinking and alerting, and neither picking up the handset nor using the speakerphone button will answer the call.
We’d set it up with the then-latest 188.8.131.52, and even after upgrading to 184.108.40.206 it’s still experiencing the same problem. I’ve currently got 220.127.116.11 on it and can now only wait for feedback from the client.
Possibly my only other recourse right now, if the complaints continue, is to repurpose the one GXP2140 in our own office, which I’m told has some relatively ancient 1.0.5.x firmware version.
