Alternative to PJSIP_HEADER(read,P-preferred-identity) for number only

Hi,

currently we use PJSIP_HEADER(read,P-preferred-identity) to work with the CALLERID the phone wants.
Sometimes this header contains a name, so CUT is not an option here.

Is there a way to get only the number from P-preferred-identity?

Have you try the ${CALLERID(num)} variable ?

I just tried and it contains my PJSIP-username…
