2) For removing +1 from incoming calls first use PBX – Incoming Calls – CID modifiers

Here you can use various rules to modify numbers. For removing +1 from start of number just set 2 in field CID Number Settings – Skip. It will ignore first two simbols in incoming calls.

Than when you will create inbound route in PBX – External – Inbound Routes and choose in field Caller ID Modifier previously created modifier
