Query on GT–
Considering IS41 networks,in SMS Call flow, when the SMDPP_MO message is received by the SMSC, it tranfers the SMS Request to the STP with the info of OPC and DPC in the Routing Label of MTP-3.Also, the SCCP part contains the GT parameters. The Called Party Address Indicator is based on GTI value for conversion of the address digits say B-Party (MDN in this case) with TT-19 (E.164 Specs)to the STP.
Now, my doubt is, that in the Calling Party Address Indicator, with the Route Index value of 1, what will be the Point Code will it be it that of the SMSC or the MSC and why?
