Some customers may have several VoIP accounts, so it is often required to use different external lines to route differnt calls. For example, for destination number 2xxx, we hope to use external line 1, for destination number 3xxx, we hope to use external line 2.
We can use MSS "dial plan" to fit this requirement.
Please click menu "dial plan / analyze called number" to add following records.
Called number prefix = 2 Route type = external line Specific external line = external line 1
Called number prefix = 3 Route type = external line Specific external line = external line 2
