I have a problem with did numbers running through asterisk.
I have a user with a range of 5 ddi.
Now when I ring DID number it`s always ring the same extension.
I think this is because fiel in sip packet.
INVITE sip:103@IP_ADDR SIP/2.0
Via: SIP/2.0/UDP IP_ADDR:5060;branch=z9hG4bK601f4eae;rport
From: “011111111” sip:03333333@IP_ADDR;tag=as17872029
CSeq: 102 INVITE
Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY
Now is there any way to change TO field to be DID number, in this packet so the system will recognize this as walid number and ring correct extension?
