messages exchanged between the two PLM home and visiting,in particular the IAM from where is it sent?,or all the messages are between the MSC and PSTN,or there is just the CAP messages with SCP?
note that i'm in case we are using Camel service.
thank you.
SCP(service control point)je parle pas de SCCP protocle.
if the IAM is sent from the MSC where the mobile is located,why ,i can see the international carrier for the home PLMN in the traces(ISUP traces) taken in home PLMN?

I'm installing a credit card machine at work – the instructions say to ensure its connected to a PSTN line, never RS232.
Can i use the same socket as i use for the fax line?
