I've seen a lot of traffic on the list recently about which phones can do supervised transfers and which cannot, and I have to admit that I'm a bit puzzled. Our existing PBX, which is software based, handles the transfer functions for our call center -- the agents never touch their phone, and instead use software. We can plug any old phone into it, and it'll work just the same. So my question is this: when people discuss the impossibility of Asterisk handling transfers, are they only speaking of SIP setups? Is it possible to do supervised transfers through Asterisk over plain old phone lines? I'm not a programmer, and since our Asterisk developer doesn't know the answer to this question, I thought I'd ask you guys. :) Thanks, Devon

The issues that have been presented are all issues with VoIP phones. SIP in particular. These phones do part of the work themselves, so features must be supported, both in asterisk and on the phone itself. -- END OF LINE

Just turn on threewaycalling and transfer in zapata.conf. Flashhook, dial the number, talk (if you wish) to the person you've just dialled (without the caller you're transferring hearing). If you flashhook again, you'll have a threeway call; if you simply hangup, the call will be transferred. -Tilghman
