[Asterisk-Users] Astersik CVS HEAD + T1 e&m wink + IAX client doesnt detect call answered on Zap channel

[Eric Wieling]

Play around with the wink= and rxwink= options in 
/etc/asterisk/zapata.conf.  Try setting rxwink=200 and wink=200 and 
stop and start Asterisk.  It looks like asterisk is not seeing a wink 
from the telco.

Do NOT use busydetect or callprogress options.
