Hi,
We have a many services in our company, each one must display a different number in his outgoing calls. We use a Asterisk SIP server.
Our SIP provider asks us to make our Asterisk server send a prefix before the outgoing number.
for exemple, for a normal call from the extension 1200, the SIP server send the number 0033123456789.
we want to make it adding a prefix for calls from each extension, for exemple add 401 before for calls from 1200 and send 40133123456789.
Can you help please ?
Many thanks.
Regards.
