[asterisk-ss7] Using libss7 to connect to an GMSC or STP

[Sverker Abrahamsson]

Well, I've been working mostly with SMS and USSD and not so much with the
location parts. To get the location information you could use MAP signaling
depending on what you want to do, the call would  be
MAP-PROVIDE-SUBSCRIBER-Info . Could also be that your carrier provide some
other interface for location based services. I guess you want to be able to
detect if a phone is active in the network or not before setting up call to
it?

 

To work with MAP you need SCCP, TCAP and MAP protocol layers on top of
libss7, I don't know of any open source implementation of them. I've used
Dialogic's products for that kind of things but it's not easy to work with.

Hi,

Ok.

accomplish on an asterisk without extensive development in which case you


would also need MAP handling.


Ok. MAP will be used to get for example the status/location of the mobile
subscriber. I understand that this part is not implemented in Asterisk.

 

Have you experienced such a case. If yes, please share your experience?




And what about the case of an STP in the place of a GMSC?


Thank you.
