hi, we are moving our asterisk from chan_sip to chan_pjsip we are using SIP_HEADER with GET_TRANSFERRER_DATA for headers from REFER (asterisk - other pbbx - SIP REFER - asterisk) https://github.com/ca4ti/asterisk/commit/4b58609c331c013845a0a61d946cbbc82092170e is it supported in pjsip too? or is there other way? thanks Marek
