Unable to connect to remote Phonebook on W52P

[Jeroen]

Hello All,

I am having some problems with connecting to a remote phonebook on the W52P

We are using
- 3CX v12 (multi tenant) PBX
- Yealink T46G phones
- Yealink W52P phones

Out Client wants to use remote Phonebook form the server.
The T46G works like a charm. Phonebook is loaded, if updatres automatically, or on demand if needed.

On the W52P, however, I put the same url as a remote Phonebook, but when I try to access it I get a "connection error!"
Both are manually provided;
The W52P is registered and working other wise.

The used URL for the hone book (some what altered to protect the innocent)
http://voip.domaan.name/%TENANTNAME%/pro...nebook.xml

We can at the moment only use http and no https, but as stated, this is no problem for the T46G

Code:

[code]Base Firmware       : 25.50.0.20
Base Hardware       : 25.1.0.0.0.0.0
Handset Firmware  : 26.40.188.1 (not upgradable apparently)
Handset Hardware : 26.0.0.7

[/code]

I cannot upgrade the handset firmware. Trying to do so (using W52P Flasher program) I get the message "Oem Version Check disaffinity, Skip Update!"

P.S. I have found several other treads with an alike problem, but sadly did not find a solution.
