I installed BulkVS PJSIP trunk about 2 weeks ago and I had the same delay when dialing outbound, I thought it is very annoying and I decided not to use it. Then 2 days ago I was poking around my system and I decided to try again an outgoing call through BulkVS. Now there is not delay. I did not change anything on my side. I guess BulkVS did something on their side.I was looking at BulkVS, did you ever get that problem solved wit the delay?
