[Asterisk-Users] transfer with threeway calling

[Michiel Betel]

Hi,

We are using threewaycalling & flash transfers over a CAC channelbank.

The following happens:

Call comes in to my extension
I talk to a party and press flash
party goes on hold, I get get dail tone
I dial internal number
internal party answers
I press flash once more
we are now in a three party conference
Or I hang up, and thus transfer the call.

Thats fine, but....

What if the internal party is busy and answers with voicemail
how then do I get my original call back to me? Pressing flash will
conf in the voicemail prompts of the internal party. Hanging up will
transfer the party to the voicemail...

Or am I missing somthing essential here??
