Call Transfer

Hi all,
I have a Trixbox setup with 2 trunks and 4 extensions, all is working well except for the transfer options, they only seem to work with the called extension,

Example"- Ext50 calls Ext51
Ext51 can transfer but Ext50 (call originator) cant.

Trixbox CE
Any help would be nice.

trixbox has not been supported for years. They took are software, put their name on it and abandoned the users.

I highly suggest that you move to genuine FreePBX (we now have an ISO distro) so you have the support of the Community and updates available to you.
