I'm working a situation where I need to rewrite my called number to a toll-free number. Because the rewriting happens after Metaswitch does the toll-free lookup, the tandem rejects the call as there's no dip.
Did you really mean called number or rather calling number? If you can hook a Asterisk box in between the device where your customers' SIP calls are coming from and Metaswitch you could rewrite either. Overwrite any calls' CLI to calling number 18009999999 and send it out to "metaswitch01" as defined in sip.conf: /etc/asterisk/extensions.conf: [incoming-calls-from-customers] exten => _X.,1,NoOp exten => _X.,n,Set(CALLERID(name)=18009999999) exten => _X.,n,Set(CALLERID(num)=18009999999) exten => _X.,n,Dial(SIP/${EXTEN}@metaswitch01) exten => _X.,n,Hangup - or - Overwrite any called number and send the call to 18007777777 to "metaswitch01": exten => _X.,1,NoOp exten => _X.,n,Dial(SIP/18007777777 at metaswitch01) exten => _X.,n,Hangup (old Asterisk, before pjsip, but not much different) Sample for sip.conf: [metaswitch01] type=peer host=sip.metaswitch.something username=maybe-username-or-leave-empty secret=maybe-password-or-leave-empty disallow=all allow=alaw allow=ulaw canreinvite=no dtmfmode=rfc2833 context=nowhere [my-internal-pbx-or-sbc] type=peer host=10.10.10.10 insecure=port,invite disallow=all allow=alaw allow=ulaw canreinvite=no dtmfmode=rfc2833 context=incoming-calls-from-customers Good luck Markus
