Solved Can't call local country numbers with +, but can with 00

[fssol]

Outbound rules only has one "catch all" rule that doesn't strip or change the numbers.

When calling internationally outside of our own country (say +3315555555 and 003315555555), both prepending with 00 and + will work fine as 3CX routes the full number to the SIP provider and the SIP provider makes the call.
When calling the local country code (say +4465555555 and 004465555555), 3CX magically strips the country code form the number when +44 is used (even though no stripping of numbers is set up in the outbound rules as the stripping happens before even matching an outbound rule according to the logs) and then forwards the stripped number (65555555) to the SIP provider who of course gives us a not found error as this number is now invalid (as it's missing a leading 0).
Dialing 004465555555 gives no such issues.

It even tells us in the log:

Looking for outbound rule: dialed = [+4465555555], processed: [65555555]; from-ext:

How do I prevent this stripping on the local country codes with +44?

More from the log:

I had to change the settings in Settings -> E164 processing to this (for the example +44):



Now dialing both +4465555555 and 004465555555 work correctly.
