I am using the latest version of ViciDial for my inbound/outbound call center and Asterisk 13 for my SIPGW. When placing calls from my Vici server, I have the ringback working for my agents on the initial call out through the SIP Gateway. If and when the agent has to conference a call or place a caller on hold and dial another call, no ringback to the agent is heard on calls going out through the SIPGW.
I have modified the context of the trunk as follows:
[SIPGW]
type=friend
host=192.X.X.X
qualify=yes
context=from-internal
peercontext=from-internal
auth=plaintext
dtmfmode=rfc2833
notifyringing = yes
progressinband = yes
What am I missing?
