cant do blind/attended transfert for external call

[Kinder]

Hi,

We found a problem today with 3CXPhone (last version 12.0.37098.0):

We can't transfer an external call to an internal extension, either attended or blind transfer : call are ended.

- blind transfer : target extension doesn't ring (IP phone or 3cxphone) and call is lost.
- attended : target extension can pick the call, but no transfer option, all greyed out (unlike in the manual http://www.3cx.com/user-manual/transfer/). Only option is "end call", call is lost.
The phone is in softphone mode, no IP Phone associated with the extension.

Transfer from other IP phone or presence screen (right clic on call > transfer) is successful.

Is there anything I missed in the configuration of the 3CXPhone v12? We migrated recently from v11 and 3CXPhone v6.

Hi there,
Can you confirm your trunk has following properties in its Advanced tab :
- Supports Re-invite : not ticked
- Supports Replace : not ticked
- PBX Delivers Audio : ticked
If not please adjust to be so and see if issue persists.

Furthermore are your 3CXPhone provisioned with welcome email ? in CTI or 3CXPhone mode ?

Hi,

OK, I unchecked the first 2 options, we will try and report back.

Hi,

Ok, it's working again.

Why was it working in 3CX v11 and not in v12? We migrated from a v11 recently.

That I can't say, but those 3 settings I gave you are default for all supported providers...
