7421 Phone 3CX

onus22 — Tue, 17 Oct 2023 07:57:53 GMT

Hello,

I have a cisco 7421 (non-3pcc version) and I am trying to connect it to my 3cx instance. I have the tftp server setup with the config file and I can see the request being made on tcpdump, but the phone report TFTP timeout on the file.

I also see the phone requesting ITLSEP<mac>.tlv and ITLFile.tlv. There is also a message "No Trust List installed"

Any help greatly appreciated, thanks

A known working SEPmacaddress.cnf.xml template can be found HERE.

Hi Leo,

Thanks for your speedy reply. I have taken that xml file and changed the ip address and such. I am still getting the TFTP Timeout message on the phone. But my logs show that it has indeed requested the files, and when I check using bash tftp then requesting the file it is available. With the ITLSEP<mac>.tlv and CTLSEP<mac>.tlv files; are these not needed? I do not have those but it seems to request them. Phone is stuck on "Registration in progress"

Cheers!

TLV files are not important to the integration of the phone to 3CX.

The mandatory files are:

1. SEPmacaddress.cnf.xml
2. Dial Plan
3. Phone firmware

Apologies, I'm a complete novice.

My dialplan is just this;

What firmware do I need? Thanks!

Is the phone getting a valid IP address?
If it can, put the phone's IP address into a browser.
go to Device Logs > Status Messages.

What is error messages are there?
