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.

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

well .. it is AS .. it can be SIP or H323 ... well if it is hooked to a PGW it is MGCP but i doubt... so it is either SIP or H323.


i will put a nickel for H323

so, you say ...

CallingParty => AS5300

A: aNum
B: didNum


AS5300 => PSTN

A: 1 + didNum
B: prefix (actually the PSTN subscriber's number)


well, without a doubt... you can manipulate whatever number you want ... you just need to find the best way to do it. This depends of the number of DIDs you would like to host. You can do a DB lookup to retrieve the prefix / Subscriber Number... or you can do it inline in your dialplan. It really depends of how much you need to scale.

Hi Michael,

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

Yes, this is the desired outcome. I was planning of using FreeSWITCH + MySQL to do this. How do I do this "inline"?

when i said inline ... i just meant to define some variables in your DP ... this is not a solution for you ... it is rather a proof of concept instead.

you need to do a DB lookup (sqlite or mysql).
