SIP On Mitel / Mitel 6869i PC Port Used For Grandstream Speakers

« Last post by bcramer on March 06, 2026, 07:21:06 PM »

I have about 14 of these Mitel 6869i phones with the Grandstream GSC3516 Speaker plugged into the PC port on the phones.

After installing these and using Multicast to page, the customer started having issue with dialing extensions. Sometimes the call will go through and sometimes they will get a busy type signal.

Got any ideas what I should look for to help with this issue?

Mitel MiVoice Business/MCD/3300 / MiVB Cluster issue

« Last post by Hus4in on February 27, 2026, 04:43:38 AM »

Hi All

I'm having issues with my MiVB cluster. Version 9.4.
When I create an extension on one node, it doesn't exist on the other nodes. Then I synced multiple nodes. Some syncs were successful, while others failed. I'd be very happy if anyone could help me.

You might want to turn debug on to see the auto answer form

If the gateway is configured properly and the telco supports 2 B-Channel Call Transfer (TBCT) it should still work, but a lot of telco's don't support this and even if they do, then their gateway needs to be provisioned properly to handle it. Honestly, this is rarely worth the hassle if the telco doesn't know what they doing.

Make sure you setup and do your Hybrid, ERL and Loss testing on the analog lines... this will likely eliminate the echo issues.

Mitel MiVoice Business/MCD/3300 / Extension auto answers

« Last post by PokerMunkee on February 20, 2026, 12:21:50 PM »

I can't figure this out.  Mitel 3300 and a 6920 phone.  I've deleted the extension, started from scratch.  I've used 3 different 6920 phones, happens on all of them.  When you dial the ext, it auto answers on the speaker phone.  If I log in with another brand new test extension, it works just fine.  I've logged my extension into the phones, it works fine.  This problem extension was assigned to a 6940 a few months back.  Issue is definitely the extension.

Any ideas where to look?

That explains it then, I just found out the Telco switched them to a PRI an unknown time ago, they are using a ATA in reverse to break the PRI into 5 analog lines that are fed into the controller so I have done all my troubleshooting assuming analog lines to the telco.

Thank you for the reply

Sounds like it is trying to do a CO Transfer... used with analog POTS CO lines that have the transfer feature from the telco for those lines. You send a hookswitch flash on the line, get a second dial tone (usually a dat-dat-dat-daaaa), dial the destination (external, no DID or extension) number, then disconnect to complete the transfer. You could test this with a buttset on the trunk itself to see if the telco has this feature enabled or not, but it sounds like they don't have that feature enabled.

This only works on analog POTS CO lines with the feature enabled from the telco... It won't work on PRI or SIP trunks

MiVoice Office 250/Mitel 5000 / Call transfer using Hookflash on 53xx phone

« Last post by JeremyJGW on February 19, 2026, 05:43:41 PM »

Hello everyone, I am working with a client who is experiencing heavy echoing once an outside caller is transferred to an extension or public number. The operator let me know that in the past one of the phone techs showed her a procedure to use a hookflash softkey to perform a transfer which reduced the echoing symptom.

I have been unable to successfully transfer using a hookflash, the procedure I found states to press the hookflash button, wait for double dial tone sound, dial your intended number then hang up to transfer the caller. In practice this is not working. I press hookflash, get one beep and dial tone, then when I dial an extension or DID the display just shows an error, I can hookflash again to get back to the caller, or hang up and the call will ring back in 5 seconds.

Is anyone familiar with this method of transferring calls on a MiVO 250 system that can fill in the gaps in my process?

smb985,

If you go to the following:

System > Devices and Feature Codes > Page Ports - You should see Page Port 1 there

You can't add one there but if it isn't there then your system is either damaged or corrupted.

Assuming it is there then go to the following:

System > Devices and Feature Codes > Page Zones.

By default, Page Zones start in the 9600 range, and you should see one here if it is going through both the phones and the page port or a trunk.

Assuming it is 9600 opening that up will show you four things.

IP/Digital Phones - This would be all of your IP/Digital phones that paging would try to go out of.
Trunks - This would be if you are using a Trunk Port to connect to your overhead paging equipment.
Page Ports - This would be if you are using a Page Port to connect to your overhead paging equipment.
Direct Paging - This is if you want to be able to direct page to any of the IP/Digital Devices.

There is another option your installation could have taken and that is to use the speaker connection of an IP/Digital phone as the connection to the Overhead Paging Equipment. If that is the case hope that they labeled the phone as Page Only or something like that.

From one of the phones you could look to see how your Page Key is programmed or do you dial a specific number to access it, that will narrow down where to look.

Thanks,

TE

I can tell you all of those items still work on MiVB 10 (v 21 + now). You'll want to make sure the MXeIII has enough hardware for the upgrade. 1Gb RAM namely. I can't remember if that was a requirement yet for v13.
