| User | Dials | Correct call route | Correct user | Mapping, number in use | Destination line | |
|---|---|---|---|---|---|---|
| 1 | VoIP telephone location A | 21 | 2# | none | 21 | LOCATION_B |
- Internal call between two VoIP terminal devices at locations A and B. The dialed number 21 matches the route 5 2# in the call routing table. The call router sends the call out over the line to the remote SIP PBX without changing the number.
