Reply To: USSD CALL

Hello Vijay,

The calledParty address of SCCP should include IMSI, refering to HLR which it belongs, with numbering plan set to E.211.

The USSD Phase-1 doesn’t support sending msisdn as part of USSD messages, where as USSD Phase-2 supports the same.

In case of USSD-Phase 2 we can use msisdn ( under E.164) addressing format to reach to respective HLR.

-Thanks
Hari
