PARK CUSTOMER DIAL 3-Way Call Has No Audio - Newest Vicibox

[callforamerica]

transfer - conf >> number to call >> PARK CUSTOMER DIAL no audio can not hear either leg and quickly disconnects without entering conference room.

ViciBox v.10.0.2 090123 ISO MD
openSUSE Leap
15.3
Using latest SVN: 3676
Asterisk 13.38.3-vici
ASTGUICLIENT VERSION: 2.14-677c BUILD: 230118-0947

Installed fresh from vicibox MD iso 1 week ago, just tested this feature now.

Login as Agent
Manual Dial to any #
then Click Transfer - Conf
then enter phone number into "number to call"
then click PARK CUSTOMER DIAL

Phone rings but when answer there is no audio either way.

This is a vanilla vicibox install, I have 4 asterisk servers all with same. Have many others clusters with earlier versions from year or so ago that do not have this issue.

I have tried turning firewall off and opening it up completely so it does not appear to be a firewall issue.

Welp, adding 88 to the 3-Way Call Dial Prefix on the campaign somehow fixed this issue! IT was previously empty. Never had to do this before but, hey it works. thank god. so not sure if its a bug or what!

Seems like every time I post on the Forum, a few minutes later I just stumble onto the answer myself. I should post quicker. hehe

Thanks for posting your solution!

Check the screenlog.0 file to see if the carrier is sending a proper Answer signal on your 3-way call, using the 88 3-way-call dial prefix forces an Answer before the call goes to your carrier so you can hear all call progress information, without it you can't hear anything until there is an Answer.
