[asterisk-users] Zaptel/mISDN and call transfer

Hi!

ECT only works after having answered a call (and having put it on hold on 
the ISDN side, not in Asterisk), see readme of chan_capi-cm for more 
info. Deflection, on the other hand, must be arranged before a call is 
answered.

I add to the wiki a tiny overview for the different methods and channels:

Of interest for you are probably:
* chan_misdn has this dialplan app: misdn_facility(calldeflect|9999)
* ZapCD for deflection as implemented by bristuff

Cheers, Philipp
