The calls that come in through the trunk have +CountryCode prepended to the phone number.
The phone numbers in the Contact Manager do not have this.
What is the least intrusive method to match the two and how do I do that?
Add the country code to the contact manager or add a method to strip the code in the trunk context, before it is handed off to the inbound route context.
I changed the Trunk context “from-pstn” to “from-pstn-e164-us”.
The number now shows up without the +1 prefix.
