Hi x-man,
thank for your reply. I set the "Dial In Trunks Incoming Digit Modification - Absorb" to 0, the "Incoming DID range" in "SIP Peer Profile Assignment by Incoming DID" I set to "420221511010-420221511019" and in "Inward Dialing Modification" I set the "Digits to Match" to "42022151101x" (Digit Length Operator = equal to, Digit Length = 12, Number of Digits to Absorb = 12 and Digits to be Inserted = 119).
With this configuration, when I dialed +420221511019 from my mobile it rang on the extension 119. So it looks the ICP is ignoring the "+" in the number and I was probably doing something wrong before.
