Mitel MiVoice Business/MCD/3300 / Teams phone integration with Unify Openscape SBC's

« on: October 31, 2024, 02:04:39 PM »

Hi, we're currently doing that for a 5000 + users. We're now at the point of fine tuning. Calls works fine, inside to outside, outside to inside (almost), but I have a very anoying thing happening to me and I have no clue what is the cause.

Here's my set-up resume: Mitel pbxs, Unify SBC, Teams office 365 infra. Got my trunk/SIP peer profile/ars route worked out, but when I was doing some testing we couldn't place call to certain cellphones providers.

In the Call routing tab of my SIP peer Profile, I setted the "Private SIP Trunk" to Yes. Since then, I can call everywhere without problem, but since the modification, I lost the ring back tone when we place a call from an device to my Teams extension. To fixed that, in the "Signaling and Header Manipulation", I changed "Require Reliable Provisional Responses on Outgoing Calls" to No and I got the ring back tone again BUT NOW instead of the extension number I see on the phone's acd screen "Private Ringing".

Look like it's a never ending series of I fixe something to create an other problem.

thanks

SIP On Mitel / 5634 wireless call problems

« on: November 17, 2023, 10:14:40 AM »

Hi, just got promoted to the telephony department, pretty green with Mitel systems, a lot a experience in IT in general. I have a 5634 phone with either a no access error or occupied line. I double checked the configuration with Winpdm. I noticed a error VoIp/SIP parameter. Corrrect it, didn't change a thing. I found that the device type in the pbx profile was at 5624 IP phone. Change it, to Generic SIP phone, the no access error went away, but now when we try to make a phone call it says line occupied and if we tried to call the phone it says the same thing.

Any one as a clue?
