Summary:                    Transfer capability is inherited by a channel after
being transfered via atxfer
Description: 
PhoneA calls PhoneB (221)
by Dial("mISDN/12-1", "mISDN/1/221|15|tr")
PhoneA is not allowed to initiate transfers at that time.
PhoneB is allowed to.

PhoneB transfers PhoneA to PhoneC(208) (attended trans) 
by Dial("Local/208 at isdn-nt-1-bcec,2", "mISDN/8/208|15|")

now PhoneA now is allowed to initiate transfers: 

for example:
exten => 1,1,Playback(tt-monkeys)
cli output: 
- Started music on hold, class 'default', on Local/208 at isdn-nt-1-bcec,1
    -- Playing 'pbx-transfer' (language 'de')
    -- Executing Playback("Local/1 at macro-dial_intern-e687,2",
"tt-monkeys") in new stack
    -- Playing 'tt-monkeys' (language 'en')



Is this a bug? a feature? or designed to behave like this?
wondering...

otherwiseguy,

there were 2 things:

1. Initialy Reported problem with 't' option
2. Problem with 'T' option - reported by you.


There was definitely a bug (wrong C code) with 1st issue - my patch fixes
it.

2nd issue is not a bug, code is ok there is nothing wrong with it. This is
how transfer was _designed_ to work. As for me i don't like it too, but i
don't see a way of fixing it in current implementation of transfer
(described in my precious posts here). 

May be you can offer a way of fixing it? i would glad to hear a fresh
ideas..

Probably we need to export some sort of API to Asterisk's dialplan, for
controlling xfer capabilities by users. But anyway - this is different
issue IMHO, more likely feature request.
