Hi Michael,

The DID is transported via SIP to the router. From the router to the POTS provider, it's PRI.

How is the DID transported? SIP, PRI, analog DID trunks?

Hi all,

Consider the following scenario: Calling party --> DID provider --> Cisco AS5300 --> POTS provider --> Called party

The Calling party calls a number provided by the DID provider. This is then processed by the AS5300 facing the POTS provider to do the following number translation: ANI = 1 + DNIS (the ANI assumes the identify of the DNIS prefixed with "1"). The Cisco AS5300 then sends a "prefix" which is actually the number of the Called party in their system (of the POTS provider). However, the Cisco AS5300 has a finite limit on the number of translations (approx. 128-300 translations). Can the number translation be done on FreeSWITCH instead?

    Calling party --> DID provider --> FreeSWITCH --> Cisco AS5300 --> POTS provider --> Called party

This can also evolve into:

    Calling party --> DID provider --> FreeSWITCH --> Cisco AS5300[1] --> POTS provider --> Called party
                                                                  \                                          /
                                                                   +-----> Cisco AS5300[2] --->+

If we wanted to increase the number of ports the POTS provider.
