[VoIP] Seize zap channel without dialing

[Donald Froula]

Shane,

My signalling is set to "sf" in /etc/zapata.conf. I
had to compile ztfg-dude in zaptel, as the regular
ztfg will not start sf trunks.

Here's my definition for both sides of the sf/mf
trunks.

I patched the Asterisk channel code to send the wink,
as it is not there for SF trunks. The initial
connection over the trunks uses immediate MF dialing,
no wink required. With my patch, the wink is there,
but is purely cosmetic. Zaptel SF was originally
designed for 2600 spurt signalling over radio links,
so is missing lots of stuff needed to support the old
system.

Thanks,

Don
