Auto provisioning - issues with proxy settings and default settings

[pbxguru]

Hello Folks!

I hope this is the right place. I'm running 5.2 on Debian 12 and things are working great. I've been working on getting zero-touch provisioning to work with our Yealink RPS and YMCS account.

So far, based on what I read in these forums, we got auto provisioning working - somewhat.

1. Reset phones find Fusion server.
2. Phones connect and download its config.
3. Most settings are configured on phones (extension, etc.)

Despite getting most configs down, we're missing proxy server settings. When manually adding proxy settings on device's portal, it registers.

So far, we have these two issues.

1. Cannot seem to enable proxy server settings. Despite adding the settings under Devices, it simply does nothing. Trying to add the following Yealink parameters:

outbound_proxy =
outbound_port =
outbound_proxy_enable =

Is the device page the best place to add proxy settings?

Another issue is Yealink's YMCS management.

2. YMCS requires at least two parameters in order to add/manage supported devices in your YMCS account. These are:

dm.enable = {yealink_static_dm_enable}
dm.server.address = {yealink_static_dm_server_address}

I have added the parameters in the T19 cfg file. I also added the missing variables under Default Settings | Provision category, but when I attempt to provision, nginx logs show exceptions:

I have flushed cache and reloaded XML, but nothing. Wondering what I'm doing wrong.

Thanks!

You're missing the dollar signs in the variables. As for the SIP outbound proxy issue, that's part of the line information along with port, etc. Shouldn't be anything necessary you need to change in the template.

(There is a brand new Yealink firmware that doesn't like sip_server_host anymore, so possibly related. Still investigating this one though, might submit a pull request if I can work out why)

Oh my gosh! You were right. I was missing the $ character in the variable in the CFG file. After updating it and clearing cache, the YMCS settings were added automatically.

Next is proxy settings. I noticed the attached blank setting in the MAC's cfg template. There is no variable set at all. I will see about modifying this and get back to you.

Thank you.

Ok, I tried updating the proxy settings on the MAC.cfg file. Only two settings are getting set (outbound port and outbound proxy). However, I can't seem to get the account_1_proxy_enable setting to set.

If I manually set account_1_proxy_enable = 1 - it works.
If I set it to the declared variable in default settings, it does not work.

Exporting all settings from the phone shows no variable for account_1_proxy_enable.
I have recreated the default setting and flushed cache.
Other two settings work.
No tag errors or exceptions in error.log
Wondering if I'm missing something.

That's supposed to be a curly braces instead of normal brackets.

That was it! I do think my eyes are failing me. I finally got my requirements working: ZTP with Yealink YMCS/RPS and FusionPBX. - Rock on. Thanks for your help.
