Mitel MiVoice Business/MCD/3300 / Re: Teleworker problem with calling in-office IP desk phones

« Last post by dmichels79 on April 12, 2024, 12:22:43 PM »

Hi Ralph,

The TW phones get audio when calling a 5330e phone in the office but not when calling a 6930 phone in the office. This all started after the version upgrade in late January of this year. I haven't seen that the TW phones can get to some phones internally better than others based on their subnet, seems to be more specific to the model of phone.

From what I can see in the MBG server, there are networks specified that covers where our internal phone IP ranges are.

This topic has been moved to MiVoice Office 250/Mitel 5000.

This is a 250 question

MiVoice Office 250/Mitel 5000 / Unable to receive or make outside calls. Sys Alarm #114 on controller.

Hello.  I'm new IT here.  Mitel HX controller.  We are currently disconnected from the outside lines - unable to make or receive calls from outside the plant.  I'm on the phone with the phone service provider (Frontier), but they are having trouble finding anything. The alarm is telling me I have lost connection, right?  We have made no changes here at the plant.

Usually when I see this it's because of a routing issue.  That is if the FW is configured correctly.
Is the problem that the TW phones can ~never~ get audio or only when calling devices on certain subnets.
Also, you may want to ensure that the network routing in the TW server know about all of your inside networks, not just the one that he 3300 resides on.

FWIW, the audio internally is udp in the 50000 range, but teleworker to remote set goes in the 20000.

Yes that is how the audio has always been done on the 3300, I think the 250 stays in the middle

Thank you johnp!

Am I understanding correctly that call audio from teleworkers inbound through the MBG server should go straight to desk phones that are on the "inside" network of the office, after the call setup and tear down takes place? Has this always been the case? I've never had inbound ports directly from MBG to in-office desk phones open before.

The 3300 only sets up and tears down the calls, all audio streams from device-device, or perhaps device-teleworker server in your case

Hi ZuluAlpha!

There is a firewall involved. The MBG server resides in the DMZ zone of the firewall, the other Mitel servers and in-office desk phones reside on the inside, corporate lan zone of the firewall. I have opened all ports for testing from MBG to internal servers and vice versa. The only way it seems that teleworker calls succeed is if I allow MBG (DMZ zone) to talk directly to the in-office desk phones (inside zone).

This was not the case prior to the upgrade in January, is this normal behavior that MBG needs to talk directly to the desk phones in the office when I call is initiated from a teleworker?

On the inside if your TW and MBG are trusted it shouldn't be an issue. Is there an external firewall involved? It sounds like it's blocking SIP to the 6900's.
