Number Mapping

Route Settings

• Force Enblock is required since overlap dialing is not supported.
• MAP Settings are required for the CLIP No Screening Settings, PPI Information must go in International format.

Known Problems / Remarks

• Redundancy: As each MSN has to be registered separately, routing for outgoing calls could be performed internally to allow bypassing failed registrations.

As this only works for outgoing calls, this feature is only rated with half.
