Avaya IP phones dialing International calls by themselves.

[raist3001]

Kindly request some help in this matter. I have searched google looking for an answer as to why IP phones are dialing international calls by themselves. They go off hook and begin dialing without any human interaction. I would think something was hacked. I have been looking over the configuration but nothing seems to jump out at me. The only thing I do not recognize in the short codes is a RELAY OFF. My thoughts are to delete this short code?

The system is behind a firewall, and the digital phones do not display this behavior. This is only happening to the IP phones. The customer needs to be able to dial international calls. And the IPO is set up to allow such.

Any one ever experience this? If the system was hacked, would it only be the IP phones? Or would the IPO be the equipment hacked?

Hey raist3001... another thing:
Go to System Status and check your Audit log under (I think) Resources. Check to make sure you don't see anything crazy in that place either.
I had a customer who had opened the IPO to the public WAN (against our knowledge) and the big hint someone was in the system was an outsider modifying Incoming Call Routes to international numbers.
