Introduction and Announcements / Hello from New England

« on: March 20, 2024, 06:26:13 PM »

Hello everyone,

Just someone that is fairly new to telecom (7 years now which is new compared to a lot of folks I see/work with). I mostly work on VoIP platforms (Broadworks, Adtrans with Asterisk, Genesys Cloud, OneCall) but dabble in some TDM stuff here and there with Pointspan and prior to that a lot of PRI/T1 handoffs from Adtrans to Mitel/Avaya/Nortels. Currently my only exposure to Mitel is that we use their IP phones (68XX series) where I work and we have quite a few of them (5k+)

Good to be here and hope to learn a bit more and talk to some of the people in the industry!

SIP On Mitel / 6867i 6.2 Firmware Interesting Issue

« on: March 20, 2024, 05:36:30 PM »

So we recently started upgrading to 6.2 firmware for our 5k or so Mitel phones from 4.0. We got through about 1000 phones without any issues but a small batch of 20 phones in this latest push ended up having some issues registering. Configuration doesn't change, the phones don't fail the upgrade as they show they are on the 6.2 load but for some reason they all display 503 for registration status which indicates a server issue.

I tested from our SBCs to the phones and confirm that UDP 5060 is open as I get a 200OK response to an OPTIONS ping. Downgrading them back to 4.0 gets them to register again. I set logging appropriately in the troubleshooting section but the log files all show up as 0KB for some reason. I did also do a PCAP from the SBCs and can confirm no registration attempts or any traffic at all from the phones to our SBCs. Doing a capture from the phone side for all ports shows only my port 443 (Web GUI) traffic and nothing for SIP at all. Anyone ever run into anything like this and have any advice?
