I need help with an IGAR setup. We have an S8720 CM 3.1 at the main site with a call center (NR1) and a call center at the remote site with an ESS (NR8). We have set up IGAR and forced it over to test. It's "working", but there is a 6 second delay from the time the called party answers the phone, and hears the calling party. There is also a 6 second delay to hear MOH once a caller is placed on hold. When I read the Avaya documentation, it states there will be a delay, but it sounds like the extra delay should be noticed on the callers side by hearing additonal rings while the call sets up, and not after the connection of the call and delayed talk path. Any insight would be helpful.
 
You are right to say that a delay is normal. The delay is simply caused by the IGAR call being set up in the PSTN. However, 6 seconds sounds like something else is going wrong.

What types of trunks are you using? Check your events log; are there any denial events relating to IGAR? Do a 'list trace' on a station you know will make an IGAR call (ie do a station-to-station call between NR1 and NR8 and trace the station making the call) and paste it back here.
 
Thanks for taking the time to look at my problem. The trunks are ISDN-PRI. I've posted 2 traces below. We occassionally see denial event 1240, but by the time the denial event shows up in the trace, the call is connected.

(1240 No response to IGAR DTMF E-sigged digits three times with no response from the far end.)
