Some of our agents are experiencing some strange incidents from time to time. They receive a call, and during the conversation they suddenly hear 10-20 seconds of ringback. This can happen up to three or four times during a session. The customers say that they hear only silence during the incident. I've only seen this happening on calls transferred from the IVR, but I can't find anything unusual in the CBC log:

Call ID: 1 529
10:03:44 Give Ringback NULL
10:03:44 Handed Over to Master Application NULL CDN: 6566 L_APP: Master_Script TRANSF INTERCALL_ID: 1317

Thanks for your help.
 
Check your MSDL cards. Had this problem a few years ago and it turned out we had a bad port on the MSDL card. This may take time to find.
 
I think the clue may be the transferred from IVR bit. You should have in the master script something like:
IF TRANSFERRED THEN
GIVE RINGBACK
WAIT 6
END IF

This gives time for the transer to complete before executing the primary.
 
I have this in the beginning of the Master Script :

GIVE RINGBACK
WAIT 2
IF TRANSFERRED OR CONFERENCED THEN
WAIT 4
END IF

Could it help to make the wait 6 secs?

Will also check the MSDL cards.

Thanks for your replies.
 
I think you have sufficient wait time. Nortelinsd may be onto something though, there may well be a bad port that's not signalling correctly and holding the call up.
