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. /Sverker From: mosbah abdelkader [mailto:mosbah.abdelkader@xxxxxxxxx] Sent: den 8 februari 2011 2:24 To: sverker at abrahamsson.com Cc: asterisk-ss7 at lists.digium.com Subject: Re: Using libss7 to connect to an GMSC or STP Hi, > I suppose you would use just normal ISUP to do the call via GMSC. Ok. > To act as a VMSC is a completely different thing and would not be possible to 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?
