[Asterisk-Users] HELP: problem making calls from legacy pbx to cisco sip phone via asterisk

[Pavlidis Savas]

Propably this is a cisco router issue.
I discovered that if a put
play line in the extensions.conf
so that it can play something before
the call is done, even
for one second, the call is working
normally.

I also played with other variables
in the sip.conf but have not succeeded
except with the play line in extensions.conf



exten => 419,1,Playback(pbx-transfer)
exten => 419,2,Dial(SIP/419)
