Good day,
our u200 always disconnect calls everyday, what possible may cause this problem. This is a major problem for it cannot record our calls in our business, please help me if you have encounter this problem. Thanks
by the way im not well exposed on this area.
Carmelo,
I would suggest you to create a ticket and ask help from yeastar technical support team. You may provide below information when you submit the ticket:
1, Where did you purchased the U200 from?
2, Did you ever contact with your device provider?
3, What is the firmware version of your U200?
4, What kind of calls do you experience this problem? External calls only or internal calls also?
5, What kind of trunks do you experience this problem?
I think more detail information you provide, the sooner you would get answers for the issue
HI Carmelo,
Is it a fix time after the call disconnect ?
We had the Problem with a Provider who sends a session timer.
You have to set Session-timers = Refuse in Advanced Settings -> Sip Settings -> Tab (Advanced Settings)
Greets
How to set this Parameter in S-Series there is only NO, Require, Supported, Forced.
Refused worked fine for me in the SOHO but in the S20 Calls are disconnect after 3600 sec (i think its the max value).
Hi sir Markus,
Good day!
We tried what you have suggested, but still we are getting this problem.
Our ip phones disconnected from pbx, it happens randomly. There is a day that we don't encounter this problem but happens most of the time like twice or thrice a day.
Thank you.
When the phones disconnect from the PBX it would be no Provider Trunk Problem. I would suggest to set up an ping tool and ping the phone and pbx the whole day. Perhaps there are Network Problems ?
Which Phones ?
Hi Markus,
We ping the pbx all the time, when problem started there is no disconnection on ping. We already change switches and router.
It disconnects all of our IP phones at the same time, we have brands like.
Yealink, Fanvil and Akuvox.
Appreciate your response sir.
Carmelo, when you mention call disconnect, does that mean the call disconnect during people are on the phone or that mean people are fail to make new calls?
You description sounds more like the Phone lost registration to the PBX. If you reboot the phone when you found the problem, would the phone be back to normal?
yes exactly it lost registration to the PBX.
when it lost its registration, those who have not dialed yet cannot call except for those who are still on call. Even restarting the phone it will not registered still.
restarting the PBX will solve the problem
What is the firmware version of your MyPBX U200? I guess there might be something wrong with the U200 firmware. One of my customer experienced similar issue before and it was caused by the memory(/dev/root/) of U200 was totally occupied by the temporary logs. The problem was fixed by upgrading the firmware to latest released version.
You can try login via SSH and execute below two commands to check the usage of the memory and disk:
free
df
See below screenshot:
If the usage of /dev/root/ is 100%, your U200 will not work properly.
Firmware Version:
Thanks.
Your screenshot looks normal. I would suggest you to ask Yeastar online support engineer to connect to your side and check this issue remotely.
Hi Oscar,
Yes I will get in touch with them.
Thank you so much for your time and effort sir.
Appreciate it.
Will send feedback soon.
Hi! Did you resolve the problem? I have a similar problem, U200 reboot randomly...
I Tried a new PBX and I have the same situation..
Thank you!
Hi Alexandret,
Yes this was resolved by our provider's support.
Check your router if it has SIP Passthrough & H.323 Passthrough, support disable this and boom it became coco crunch. I mean it addressed my concern.
