Allowed Country Codes not Blocking

[aits-tech]

Hi,

I have a list of 3 countries to which calls should be allowed, but the rest should be clocked.

If the call is set to dial out using 00<country-code> - and the call is not in the allowed list, the call is still forwarded to the trunk.

If the call starts without 00, then the rules apply and gets blocked by the country restriction.

I need all users to use 00<country-code> when dialing international codes and want to block them to a limited set of countries. How can i correct this functionality?

I also have E164 processing enabled as follows:

Country Set
Remove if Same country Ticked
International Dial Code: 00
National Code: 0

Anyone else having he same issue?

Thanks!

How are you outbound rules set-up to deal with number that include, and don't include the 00 prefix? Is it required by your trunk provider? Do you add it in the rules if missing? How does the Activity Log, of a blocked (no 00) and a non-blocked (adding 00), if you compare?

Hi Ieejor,

Outbound Rules are set to capture "00" and strip it out. Provider requires E164 format for all calls (excluding the +). I have E164 processing enabled in 3cx, so in this case, local numbers in E164 format are converted to local number format before hitting the outbound ruleset, so at that stage, I prepend the international code again to them.

At this stage, I technically could just use the outbound ruleset to define the exceptions I want, but would have been good to have it done from here. With my current configuration it seems like this feature is not working as it should.

Off hand, I'm not certain at what stage the international blocking is applied. From your issue description, I have to assume it is before the call reaches the outbound rules, but I haven't really had to delve into that before. I don't recall seeing a lot of posts with regards to blocked country calls, getting through, so I have to assume that there is some other option that is missing/misconfigured in your system. Were the Activity Logs of any help?

Hi @aits-tech

Just to clarify, have you gone to Settings > Security > Allowed Country Codes and made sure to only tick the countries you are interested in?
