[Asterisk-Users] Grandstream Early Dial

[Michael Sandee]

This is called overlapdial in zaptel. It works on all zaptel cards i've 
tested so far, also the zapbri cards. Chan_capi supports it aswell... 
(called Early B3 iirc), and with the iaxy it is no problem either... (it 
starts a call when picking up the hook)

So, if there is a problem... it is either the chan_sip or grandstream 
firmware... personally I would like to see this work. By the way, you 
don't HAVE to press send... if you just wait it will time out and start 
the dial procedure.

Greets,

Michael
