Trunk provider blind transfer from AA using hook flash

[mark_t]

Hello,

I'm hoping to able to accomplish the following:

Obi device located at a branch office with PSTN and anlog phone.
The PSTN line supports Call Transfer.


PSTN caller connects to Obi Hears "Press 1 to Connect to Main Office To connect to branch office press 2 or just stay on the line"

I've search the forum for an answer; the closest I've found is this:

which doesn't seem to be resolved.

Does anyone know if this is possible?

Tx,
