Remote directory recursion depth limit - Yealink T46G

[levstik]

Hi all,

I couldn't find existing topic about this issue through search, so I'm opening a new one.

Affected phone model: T46G IP phone, firmware v. 28.82.0.20.

We're experiencing an issue with the remote directory. We have an external XML generator to generate our phonebook entries and we set it up in phone using the URL link under "settings/directory/remote phone book" setup. An example of generated xml is attached. Each group/contact that is displayed gets unique URL and travelling through groups basically means accessing different url-s.

The problem is, when there are more than 3 sublevels/groups, phone displays "Fail" message after trying to access the contact/group that's below the recursion limit.

So for example - remote directory:
1. group1 (level 0)
group2 (level 1
contact1 (level2)
cellPhone +2342938429834729 (this works fine, we can navigate to this cell phone no problem)

2. group1 (level 0)
group2 (level 1
group 3 (level2)
contact1 (after selecting this item, it displays the "fail" error message)
cellPhone +2342938429834729 (we can't get to this cellphone)

Whenever there are more than 3 groups before reaching the work/cell phone numbers, it will fail to navigate more deep and display the phone numbers. Is this a known issue or is it a feature and it's limited for a reason?

What can we do, except having maximum 2 subgroups for every partner contact?
Photos displaying phonebook and exception are also attached.

Please, could you give us some clue or suggest how to fix this problem or point us to the right firmware version if this error was already fixed?

Thank you,
