Custom caller ID without country code on international calls?

[bananflue]

Hi.

I have successfully set up asterisk with SIP Trunk and custom caller ID works fine when calling numbers within the United States (SIP Trunk from US).

When calling a US number, the custom caller ID shows up as specified in asterisk config on the recipient phone without country code (+1).

However, I want to do international calls as well with custom caller ID, but when calling international numbers and specifying country code (0045 for Denmark etc), the number shows up as +145<number>. I cannot seem to find a way to get rid of the +1 country code.

Is this possible? I do not have any DID's as these are only used for incoming calls from my understanding, and I only care about outbound calls.

Do I have to get a SIP Trunk provider from each of the countries I wish to call to set a callerID that will show up without country code on the recipients phone or can I do some magic in the asterisk configuration files?

For reference, here are my configuration files:
sip.conf: https://pastebin.com/7Wsw4Z9L
extensions.conf: https://pastebin.com/sTj0vsiD

All help and suggestions/improvements to config files are appreciated as I am new to VoIP.

My recommendation would be to install 3CX and try your configuration there. If you have only one custom caller ID then it is very easy to set it up in 3CX using outbound rules.
