Hello Treesa,
Ok now i see what you want to do. I dont think that you will get this to
work with the modules asterisk allready have. Maybe you should take a
look at something like Sigtran or SDH over IP so you can transport the
pure BSSAP over ip to your MSC without needing a PDH or SDH connection
there.
But i wouldnt trust this connection for clocking. Dont forget the BSS
has to be synchronised to all the base stations and also the MSC or you
will get a lot of trouble with this.
best regards
Stefan

Hello Stefan,
I need to convert the BSSAP over SS7 messages to SIP. This
should happen at BSS only and not at MSC. So that's the requirement.
In this scenario, can I use the asterisk server? Also, which channel
modules
will I need? Kindly help me out. Thanks in advance.
regards,
Treesa

plain ISUP which could be handled from libss7.
