Hello,

I have a doubt on ISUP to SIP mapping [RFC-3398], please clarify my doubts... 

1)It tells the concept of developing SS7 - SIP gateway, i want to know the 
practical implementaion of this apporoach, are the companies already deployed 
this in the network? 

2)now we are calling from SIP phones to noramal PSTN phones.is that uses this 
concept?

3)coming to the transport of ss7 over IP, two options r there SIGTRAN or 
SS7-SIP gate way, which technology is deployed in the network? clarify the 
differences between them?


thanks in advance...
Ravi Kumar
