[Asterisk-Users] transfers with zap channel

[Paul Fielding]

Ok, I've seen discussion before on doing transfers (attended and unattended), there seems to be much confusion over it.

As things sit, I've been trying (unsuccessfully) to do transfers with a zap channel (analog phone attached to TDM400).  I have no idea what I'm missing.  My current understanding is that I need to have transfer=yes in zapata.conf, do a flash hook, dial the 2nd number, flash hook again and we're linked (attended).   Then if I hang up the call will be transfered.

However, when I try to do this things don't work.   Here's what I do:

- connection is made between Zap/3 (analog phone) and Zap/1 (outside line).
- flash hook to get dialtone (I do get dialtone)
- attempt to transfer to extension 7007 - I dial 7007
- after dialing the 2nd zero, and before dialing the 2nd seven, I hear Asterisk announce (seven - zero - one) and then Zap/3 is hung up (I get a busy signal).  Zap/1 gets parked.

Here's what the log shows:

    -- Zap/1-1 answered Zap/3-1
    -- Attempting native bridge of Zap/3-1 and Zap/1-1
    -- Started three way call on channel 1
    -- Started music on hold, class 'default', on Zap/3-1
    -- Attempting native bridge of Zap/3-1 and Zap/1-1
    -- Starting simple switch on 'Zap/1-2'
    -- Started music on hold, class 'default', on Zap/3-1
  == Parked Zap/3-1 on 701. Will timeout back to dostuff,7001,1 in 45 seconds
    -- Added extension '701' priority 1 to parkedcalls
    -- Playing 'digits/7' (language 'en')
    -- Hungup 'Zap/1-1'
  == Spawn extension (dostuff, 7001, 1) exited non-zero on 'Parked/Zap/3-1<ZOMBIE>'
    -- Stopped music on hold on Parked/Zap/3-1<ZOMBIE>
    -- Playing 'digits/0' (language 'en')
    -- Playing 'digits/1' (language 'en')
    -- Parking call to 'Zap/1-2'
    -- Hungup 'Zap/1-2'
    -- Stopped music on hold on Zap/3-1
  == Zap/3-1 got tired of being parked
    -- Hungup 'Zap/3-1'

I'm not sure what I'm missing.  Apparently something to do with parked calls, so I must be misunderstanding how do to the call transfer.

I've also tried enabling Asterisk transfer on the channel (exten => 7010,1,Dial(${CORDLESS},20,tT)).
My understanding of this method is that this allows one to hit the pound (#) to start a transfer.  Yet pound does nothing.  Is it fair to assume that the tT only works on SIP channels, or am I missing something else.

Any help is much appreciated....
