Why does a Sx80 registred to a Expressway v.X8.11 makes double calls?

Hello. Can someone give me a hint how comes that it makes one traversal call and one none traversal call on the same session?

Let me know if i am leak of information.

Do you actually see 2 outgoing sip invites or do you just look at the search history page?

Its 2 outgoing calls, not just in history. Looks like this. for exampel

I cant access the infrastructure or EP, becoz its a external customer, i have to rely on given information.

When I have seen similar behaviour in the past it's usually been caused by poorly designed and implemented transforms and search rules.
