I've had the opposite problem. Press mute while the call is still ringing and it will say "MUTE" on the display but the microphone is not muted. It was very embarrassing to discover this bug.

Re: [asterisk-users] Grandstream GXP2000 Loses Connectivity
I want to make sure that 192.168.1.10 is the IP of the asterisk machine. Anyways without looking at the phone's config I'd recommend you switch to a newer Asterisk 1.2.x release at the very minimum (I suppose it would be a "best practice" to recommend 1.4, however) all you will need is a very few minor tweaks to your configfiles. All the SIP peers can remain unmolested. I have not had issues with that and recent GXP-2000 firmwares. But maybe if you post the configuration file of the phone there might be some settings to affect this. I find it odd the phones do not attempt re-registrations after it fails.

I am using about 70 Grandstream GXP2000 phones on 1.1.5.15 code with * 1.4.16.2 and have not experienced any of these issues. The one thing that I would suggest is make sure that you are using RFC2833 for you DTMF Mode.

Re: [asterisk-users] Grandstream GXP2000 Loses Connectivity
One thing to keep in mind is that the Grandstream's firmware is notoriously buggy and unreliable. I've got one GXP2000 here that is on the 1.1.5.15 firmware, and I wouldn't even consider upgrading other phones to them. Unfortunately, the quality of the Grandstream firmware is appalling and doesn't seem to be getting any better - if anything, the stability is getting /worse/. My advise for what it's worth is to use the Grandstream phones to their best purpose - as a doorstop (albeit for a fairly light door) Peder @ NetworkOblivion wrote: > I hate to reply to my own message, but I have some more info from > debugging.

Re: [asterisk-users] Grandstream GXP2000 Loses Connectivity
I hate to reply to my own message, but I have some more info from debugging. A Grandstream tries to register and uses a nonce and it is accepted by *. The next time it tries to register, it uses the same none and * says "SIP/2.0 401 Unauthorized". The Grandtream says "ok, here try this new nonce" and then it works again. Again, the next time it registers, it tries the old one and gets slapped again and gives a new one. After some indeterminate amount of time, the Grandstream actually tries to use the same nonce 3 times in a row. Once it works, the next time it gets a "SIP/2.0 401 Unauthorized" and then the third time, it gets a "SIP/2.0 403 Forbidden". This evidently causes the Grandstream to completely give up registration as once * sends this, the Grandstream nevers tries to register again. I've waited for 1-2 hours and it never tries again. The "Forbidden" response appears to kill registration until the Grandstream is rebooted. Has anybody else seen this? Or maybe know how to get around it?

Re: [asterisk-users] Grandstream GXP2000 Loses Connectivity
I did post most of that. Point to point T1, no firewalls and no nat, cisco routers, bandwidth is monitored at 30 second intervals and never exceeds 50%, almost always 25% or less. The key is that I get messages from * like "failed to register" and it is from the IP of the phone, so it is like the phone is sending some messed up message. Asterisk is old, 1.0.3, but it has been stable for 2-3 years with zero issues. While it could be a asterisk version issue, I have 100-150 phones on it, mostly Cisco 7940/7960 and none of them have these issues. The only phones with issues appear to be Grandstream and they are all running 1.1.5.15. Here is a sample sip config: [7834-1] context=HASKI-LD type=friend callerid="HASKI" <7834> username=7834-1 secret=47834-1 host=dynamic [EMAIL PROTECTED] canreinvite=no qualify=yes Here is one of the log messages: Feb 11 18:18:05 NOTICE[20905]: Registration from '' failed for '192.168.2.165' That message is from a phone that is set to register every 5 minutes. It's been 50 minutes and it still hasn't re-registered. If I reboot the phone, it will register right away... Any ideas? Peder Andrew Joakimsen wrote: > Yes but network issues are still possible.
