asterisk users - Oct 2005 - ECT - Specifying the transfer destination.

Hi

I have just a quick question on the README for the chan-capi-cm-0.6
relating to ECT.

In the first example case -
i.e.
        exten => s,1,capicommand(ect|${MYHOLDVAR})

how is the destination number specified ? Is it implied somewhere ?

.... snippet from README ......

ECT:
    Explicit call transfer of the call on hold (must put call on hold
first!)
        Example:
        exten => s,1,capicommand(ect|${MYHOLDVAR})
         or
        [macro-capiect]
        exten => s,1,capicommand(ect)
        [default]
        exten => s,1,capicommand(hold)
        exten => s,2,Wait(1)
        exten => s,3,Dial(CAPI/contr1/1234,60,M(capiect))

.................................

thanks for any help,
best regards,
John.
