Change incoming CallerID

Hi All,

I really hope someone can help me with my problem. I search and try many hours before I post this help question so I know there is already a lot about this on this forum but sadly it won’t help me.

The company who deliver an SIP Trunk to me is sending incoming CallerID as 0031xxxxxxxxx. When I send this incoming call’s to mobile, the ID of the caller would be +0031xxxxxxxxx so I can’t call this callers back without changing the number. Did anybody know how I can change this?

I allready try a lot in extensions_custom.conf but didn’t finish with a good working solution yet.

Many thanks by forward!

Look at and modify a custom context based on

[from-pstn-e164-us] in /etc/asterisk/extensions.conf, you will need to rewrite it to suit your locale as

[from-pstn-e164-nl] in /etc/asterisk/extensions_custom.conf to suit and send your inbound calls to that context.
