We are using Asterisk PBX 11.21.1 integrated with geneys outbound engage we are facing a strange issue when dialing predictive using genesys outbound we get a SIP/2.0 480 Temporarily unavailable which we are unable to figure out where the problem is

I suggest you show us a SIP trace of both the Invite you are sending, and the
response you are getting - otherwise we are looking at a “Temporarily
unavailable” response (which for all we know could be quite correct) without
knowing what you requested in the Invite.

“Well, I shouldn’t really tell you this, but… no.”
The 480 coming so quickly in response to the INVITE most likely means something on the B side of Asterisk is down or rejecting the call. It’s going to be pretty difficult to know more without a trace from Asterisk itself.
Yes I understand but the problem is that out of 5000 calls when dialed in predictive mode by geneys outbound solution wherein the pacing ratio is set to 5 calls per agent it results in 1000 calls being answered and the rest as 480 temporarily unavailable which is quite strange as it is not that every outbound predictive call results in dropped on no answer
Well, again without a trace from Asterisk we can only speculate as to the cause of the 480 responses, as 480 is quite generic. We don’t even know if Asterisk is generating the 480s based on a condition or if they are coming from the upstream connection.
