exten => _.,n,Set(ACTUALTO=${CUT(MESSAGE(to),@,1)})
exten => _.,n,MessageSend(${ACTUALTO},${MESSAGE(from)})
exten => _.,n,NoOp(Send status is ${MESSAGE_SEND_STATUS})
exten => _.,n,GotoIf($[“${MESSAGE_SEND_STATUS}” != “SUCCESS”]?sendfailedmsg)
exten => _.,n,Hangup()

exten => _.,n(sendfailedmsg),Set(MESSAGE(body)=“[${STRFTIME(${EPOCH},%d%m%Y-%H:%M:%S)}] Your message to ${EXTEN} has failed. Retry later.”)
exten => _.,n,Set(ME_1=${CUT(MESSAGE(from),<,2)})
exten => _.,n,Set(ACTUALFROM=${CUT(ME_1,@,1)})
exten => _.,n,MessageSend(${ACTUALFROM},ServiceCenter)

It form

PJSIP:202 send message to PJSIP:101(offline)
when pjsip:202 send fail, the system will send a new message to pjsip:202 in expected. But It not happened
It is work on chan_sip and asterisk 13.
Sending failed msg doesn’t work in asterisk 18+
please help

You have 1, not 102. What is is in the From header in the actual MESSAGE request from the phone?

I meant 202, not 102.

However you should be sending to pjsip:202, not to sip:202, for whatever 202 should really be. The dirty way of doing this would be pj${ACTUALFROM}

sorry i fix the demo number。

PJSIP:202 send message to PJSIP:101(offline)

perhaps there are some error in here.

You are still trying to send to chan_sip, not chan_pjsip. See previous reply.

exten => _.,n,MessageSend(pj${ACTUALFROM},ServiceCenter)
It works when I add pj.
It only has a WARNING,
WARNING[14336]: res_pjsip_messaging.c:719 update_to_uri: To address ‘[email protected]’ is not a valid SIP/SIPS URI
It may not matter

Thanks. David
