PGW & Siemens

exchange1 · ‎02-15-2007

I have a PGW connected to a PSTN (Siemens EWSD) for a prepaid calling card platform. I can dial into the cisco platform but when I route the call back to the same PSTN, the PSTN sees the calling number prepended with 009.

Below is the SS7 trace from the PSTN showing the owner DN 00915925 instead of 15925 (Although I noticed in the trace the NAI is international while the PSTN is expecting national).

I need help,

This is because number normalisation is configured in your trunkgroup that is "responsible" for processing this call.

I am able to resolve the problem by setting the NAI to "national" which corresponds with what the PSTN wants. Since my PGW is in signaling mode I used the command "linexlate" to make the changes.
