Hi List Implementing screening and routing I have stumbled over this issue:
[pbx-router] exten => s,1,NoOp(ROUTER FROM: ${CALLERID(Number)} TO: ${DESTINATION}) same => n,Set(SOURCE=${CHANNEL(name)}) same => n,Set(PAI=${PJSIP_HEADER(read,P-Asserted-Identity)}) same => n,Set(FROM=${CALLERID(Number)}) same => n,Set(TO=${DESTINATION}) same => n,Set(DIVERSION=${PJSIP_HEADER(read,Diversion)}) same => n,AGI(router.agi) same => n,GoTo(dial-out,s,1) [predial-handler]; Manipulate Header on OUTBOUND channel exten => screen-update,1,NoOp(PREDIAL FROM: ${CALLERID(Number)} TO: ${DESTINATION} PAI: ${PAI}) same => n,Set(PJSIP_HEADER(update,P-Asserted-Identity)=${PAI}) same => n,Return [dial-out] exten => s,1,NoOp(DIAL FROM: ${CALLERID(Number)} TO: ${DESTINATION} PAI: ${PAI}) same => n,Dial(PJSIP/${DESTINATION},,b(predial-handler,screen-update,1)) same => n,HangUp() router.agi does perform among other things like emergency location routing: _screening_. It checks if the FROM and PAI sent from the customer correspond to phone numbers assigned to that customer and if not, replaces them with the correct values, also taking account customers with clip-no-screening agreement (they can set 'From' maybe also screened to some allowed number ranges, but PAI is 'Provider provided, Network screened' therefore we MUST set this to the customers real phone number) I can correct ${CALLERID(number)} on the calling channel and this is preserved on the outgoing channel. But I have not yet found any 'easy' way to pass the corrected ${PAI} Variable to the callee channel.
