SIP to Mobile Fail - 1191 Network Failiure

G650

We have an intermitant issue where the SIP calls to mobile fail, on the trace below station 5011 dials a mobile number, if fails they hang up the phone dial exactly the same number again and it works.

I have contacted the SIP provider Verizon and they have just come back and said this is a Avaya issue, no more details i am waiting for a response to my question of if they could even see the calls hit the network.

All calls run through an SES server but the SBC is hosted at Verizon. I have copied in the route pattern which although has options 2/ 3 in it you can see they are not used. I have also copied in trunk group 98 where the calls are sent out to the SES.

If you have any questions about the SES server please ask,
SES Version SES-5.2.1.0-016.4
System Configuration Simplex
Host Type SES combined home-edge

Link Portocol TLS is ticked
Listen Protocol UDP is tixked, TCP is ticked but greyed out and TLS is ticked.
