SIP Trunk Issue

Howdy All,

Having an issue with a SIP Trunk on a U100. Basically on occasion the internet link drops out for whatever reason - once it's reconnected however the SIP trunk remains in failed mode, until you physically login to the PBX - > edit the SIP trunk and re save it again which forces it to reconnect.

Is there a way to set it to retry the connection periodically?

  Troy,

   

  See below screenshot:

  

  Check what is the register attempts you configure on the SIP settings page, try setup that setting to 0 and see if that would help.

  Hi Oscar,

  Thanks for the quick reply. Just checked the settings and they're set to 0 already.

  The exact scenario that occurred was we had a power outage, the PBX comes back online prior to the modem getting sync, and thus the SIP trunk fails. The modem comes online shortly there after, but the SIP trunk remains offline.

  Hi Troy,

  If so, I would suggest you to capture SIP packets before the power outage and after the power page(capture packets for the whole procedure would be better), and check if the MyPBX send correct SIP register packets to the SIP server or not.

  Does the problem happen every time the power outage happen?

  Does save and apply changes for the SIP trunk fix the problem every time?

  If yes, I think we can make a temporary solution by force the MyPBX to apply changes (actually, it is reload the system configurations files) after the power outage happen (Power outage will cause MyPBX reboot, we can write a script to request MyPBX to do the reload after specific time).

  Hi 

  I am experiencing the same problem at a client. We even tried WAN failover on external Router. Still having the same problem.

  Register attempts tried on both 0 and 20 000.After ISP reboot or WAN Router reboot U100 does not automatically Connect VoIP Trunks. Have to reboot U100.

  This is becoming a serious issue for my client and he requested that I have to replace the U100 with a different brand

  Werner,

  What is the firmware version of your U100? You can try update the firmware to latest version and see if that help. If not, I think you may would like to try schedule reboot the MyPBX U100, see below article for reference:

   HI Oscar,

   

  We are a VoIP provider for call center solutions till now which typically ran off web based diallers and softphones etc with no problems. However ive given pabx installers access to our voip and they all yeastar fans. The above mentioned problem is a sore one for me. Can i please ask you for a step by step solution in your suggested order to get the pabx regsitered again? The Yeastars are run directly to LTE which we all know dips a few times.

  Hello,

  I also have the same problem with some client with a less stable connection, when the client loses internet some time it does not seem that the SIP trunk tries to reconnect to the SIP server.

  I experienced this on some S-Series PBXs

  here is the configuration of not SIP page

  the only way to make the trunk work is to disable and re-activate the trunk.

  can you test this internally for a solution?

  Thanks

  And I have exactly the same problem.  I do have a ticket open with Yeastar.  (201807612) But they dont seem to understand that when the link (trunk) drops that it should "re-dial" to bring the trunk up.  I have to do the same thing to disable and re-enable the trunk to bring it back up.  Thinking about returning the unit and going with FreePBX system.

  We are having the same problem currently using U100

  Even the vendor cannot convince and guarantee that newer S100 will solve the problem

  We are very truly disappointed
