A few weeks ago I bought a BNIB (brand new in the box) Mitel 5235 phone, intending to get it to work as a SIP phone with my FreePBX 15 server, as I know others have done. The phone sat on the shelf until yesterday when I tried, unsuccessfully, to get it to download firmware from my t*f*t*p server. I'm thinking that the firmware on the 5235 is very old, maybe too old.
Aside: Note that I have a Mitel 5330e, and have downloaded the 8.0.0.4 firmware using t*f*t*p, brought up the Web Configuration Tool using the IP phone's IP address, and the 5330e has registered with FreePBX. So I'm relatively familiar with booting Mitel phones, and configuring DHCP options for Mitel IP phones on my pfSense firewall. Here is ta link to a description of the procedure I used:
FreePBX 15.0.17.24 / Current Asterisk Version16.16.2 / all modules up to date / pfSense 2.5.0 On a whim, because it was inexpensive, I recently bought a Mitel 5330e IP phone. I thought I might try to get it to register with FreePBX. I did a fair amount of searching with Google to try to be...

On the 5235, when I view version info, here is what I see:
Main Load Version: 00.00.00.00 [Yes, all zeroes]
Boot Load Version: 01.00.00.41
L2Boot Load Version: 01.00.00.41
I'm wondering if anyone has any insight into how I might get the 5235 working, or where I can find firmware older than 8.0.0.4, say 7.2.0.4 or earlier.
