We have Microsoft 365 A5.

I think it sorta/kinda includes Teams PBX.

Does anyone know what's included with A5 in regards to PBX and what isn't included? I am trying to do a cost comparison to our current SIP trunk.

The more I read about Teams PBX, the worse it seems.

1. User has to sign into Teams native phones?

2. User has to get an auth code to sign into SIP devices?

3. MFA must be disabled for common-area SIP devices?

Teams PBX sounds like a solution Microsoft employees put together against their wills.

Went full retro last night and dialed into a BBS via 2600.network from Australia to the USA.

Given the “phone line” is an analogue port on my NEC PBX and external lines are SIP trunks these days I didn’t expect it to work - but it did at 24000bps!

Why is it that Major PBX vendors like Mitel and LG/Nortel have terrible, non-compliant SIP interfaces? Get your act together!

I'm playing with a couple different cloud based PBX systems to offer my customers. Any recommendations from the masses? #pbx #telephone #voip #cloudpbx #sip

Enterprise “phone system modernisation” = $500K + 18 months to rip out your Cisco PBX.

SIP integration = Point your existing infrastructure to an AI endpoint. Deploy voice AI in hours, not months.

Keep your PBX. Keep your carriers. Add intelligence.

Most voice AI requires expensive number provisioning. VoiceInfra deploys differently.
Deploy AI agents on existing PBX extensions:
✅ Ext 201 = AI receptionist
✅ Ext 301 = support
✅ Ext 401 = booking
Works with 3CX, Asterisk, and Avaya in minutes.

Last night I got the One Per Desk connected to the outside world.

Not really impressed by Twilio.

Thought I would try them for providing SIP service to my PBX, and after upgrading to from the trial to the personal account, they disabled everything related to voice. The only way was to upgrade to a business account.

This was after going through Persona's […]
