I would like to know the use of SSN in SS7 network.

Also, I have a ICM prerouting scenario, I need to configure my PGW and ICM NIC with a SSN. Please let me know what value i should use in SSN field.

Can you post an example?     I have not seen an example of this.   I could mistaken, but I dont think CUCM or gateway will look at this level of the SS7 to handle routing.  I believe its only looking at the transport layers to setup the call and monitor it.  The actual digits dialed or routed happen at a different level.  (all though I could be off on this)

Sorry, I just noticed the PGW.....  I have not worked with this device....  hence my reply probably does not make sense.

Hopefully someone has answers for you.

Here is the topology,


PGW<-------->ITP<----------->ICM NIC

PGW is connected to cisco ITP (2811 router with special ITP image) via ethernet. ITP is conncted to ICM NIC using V.35 cable. both talk traditional SS7.
