Solved during a call: the call is often/suddenly switched/replaced to another a extension

[user009john]

Hello,

customer claimed about jumping call (during a call)

He reported, that sporadic (during a call) the external participant B) hears the 3cx-hold-music and then participant B) will be forwarded to random extension(internal collegue)
Under "Reports" it is visible, there is "participant B" was replaced by "random extension(internal collegue)"
I have also an 3cx-activity-log about this error. (it was luck that it happend to me) (the customer said it happens often during a week)

It is v18 DebianVM, with 20x SNOM D345 and all on premises.
no Softphone/no Smartphone App use.
SIP Trunk is deutsche telekom company flex sip-trunk.

Do you have a idea about it?
Thx + Best Regards

What does the Activity Logs show happening?
Doe this happen with calls to one particular extension only? If so, I would replace, or swap, the physical set, with another extension, to see if the issue stays with the set, or extension number. It may very well be a faulty phone.

>What does the Activity Logs show happening?
OK - I will post it later

>Does this happen with calls to one particular extension only?

around 2-4 snom-3cx-users claimed/reported it.
I doesn´t asked the others whether they never experienced it. (not 100% sure whether "ext. 22 replaced ext 15" in call-report allways is the error)

I factory-reseted the SNOMs and re-provisioned them.
I doesn´t deleted and re-created the exention in 3cx yet.
It was a v16 Windows installation, config was imported to v16 debian and v18

Hello,
it was solved via reduce all "not needed rights/settings" + delete/purging/recreate some users"
