ec500 behaves strangely in Ireland

[Zastruga111]

Stations using ec500 in Dublin and routed through a local PRI ring the cell phone correctly but if you pick up the desk phone
you still hear the cell phone ringing.

Can you post a list trace of the call and paste in the code tags

like this?

Even better if you can mark where in the trace timing you picked up the phone set and heard ringing still.

I wonder if your PRI is seeing the call as answered/active on the cell phone even though the carrier is in reality still routing it.
