[asterisk-users] attended transfer unreliable

[Stefan Friedrich]

Hi,

running asterisk 1.2.9 with freepbx 2.1.1, I have a strange problem:
sometimes, call transfer works as expectet, and sometimes not. So far, I
couldn't figure out any pattern in this behaviour,

features.conf:
featuredigittimeout => 1500
atxfer => *3
-----------------------------
works:
