SIP On Mitel / 5330 Firmware Issues
« on: August 10, 2018, 01:09:55 PM »
I’ve done a lot of reading on the Mitel Forums but I’m a bit out of my depth and just can’t quite get a Mitel 5330 to do what I want. Prior to this I knew very little about Mitel and nearly everything I have learnt so far I have gleaned from here :). Thank you to everyone who have participated.

So, I’ve got a Mitel 5330 in SIP mode that I want to use as a stand-alone device at home connected to a SIP provider called Sipgate.

Following all the valuable information and the linked files in http://mitelforums.com/forum/index.php?topic=2800.0 I have managed to upgrade the firmware to:

Main: 05.02.01.05
Boot: 05.01.00.17
L2Boot: 06.01.00.09
DSP: 3.0.0.20

I have full access to the web gui and I am able to configure it. It shows I’m on SIP firmware R8.0.05.02.01.05

When I populate the various Sipgate setting the phone works correctly but then after a while it starts to flash “No Reg” in the top right corner. If I reboot, it works again for a while then “No Reg” comes back. I’ve tried every combination of setting I can think of including setting Sipgate’s STUN server as I’m behind a NAT connection, but whatever I do “No Reg” comes back after a while and I lose connection.

I tried the same settings on a Grandstream phone and it’s remained connected.

I thought I’d try upgrading the firmware on the 5330 to get a newer version of Boot and Main etc so I connected to dikie’s MBG as mentioned in another post that he has kindly made available to use. I managed to upgrade to:

Main: 06.03.03.10
Boot: 06.04.01.02
L2Boot: 06.01.00.09
DSP: 3.0.0.21

However with this version there is no longer any web gui for SIP mode so I can’t configure anything as I reset the device and all of the setting. Also the settings menu options available via the Superkey are missing. I tried reinstalling it a couple of times more but with no success in fixing the issues. I can ping the phone and even telnet to it. 

So I decided to put the older version back using Tftp running on my PC and it was back to as it was. I configured it again via the web gui and it worked again but still flipped to “No Reg” after a while.

I then decided to try upgrading to the newer version again using the option in the web gui but this time I did not reset the settings to default. I’m now back to the newer version with the bow tie logo, still don’t have the web interface or settings under Superkey, but as the SIP settings are still there from before I’m able to use the phone. However, now it no longer gives the “No Reg” error and has remained connected (so far). 

Does anyone have any ideas of what I should do next?

Thanks,
Al.
