Hi,

Thanks for your response.

Does the corresponding SS7 primitives holds good for the scenario explained
in previous mail.

So on receiving INACTIVE from ASP, the SGP sends

 MTP- PAUSE primitive is sent if the route is based on dpc.
 MTP- UPU primitive is sent if the route is based on dpc and SIO.

Sandeep B S
