Transfer and Blind Transfer

[Axion Communications]

Currently when you define a dss or memory key as transfer. The transfer type is determined by the value of "transfer.dsskey_deal_type". It would be much better if there were a type for Attended Transfer and a different Type for Blind Transfer.

This is an extremely common request from our customers. They want to use attended transfer for extensions and blind transfer for voicemails.

In order to not break any existing functionality, I would recommend leaving the behavior when button type is set to 3 as it currently is. And adding new button types (47 and 48) for attended transfer and blind transfer respectively.

This would help us sell even more Yealinks. Cisco and Polycom currently supports this functionality.
