Hi to All!
Sorry for my English first! :-)
I'm using SPA504G phones with IP-PBX ZyXEL X8004. One-touch buttons is configured as described in manuals: fnc=sd+cp+blf; sub=UserID@$PROXY
Here is my problem: when I want to transfer incoming call to other extension by pressing desired One-touch button, it executes a BLIND transfer, not attended transfer. There's two interesting fields on SIP tab of the web interfacenamed 'Hold Target Before REFER' and 'Keep Referee When REFER Failed', but changing of values of them does not changing result.
Please explain meaning of these fields to me, how it works and what should I do to retrieve ATTENDED TRANSFER by pressing One-touch button.
Thanks a lot!
Ruslan
