Hi All,

         I have a few queries bout IN-CS2.

1. What exactly is done in the OBCSM pic Authorize_Call_Setup, is it only required for Continuty check for ss7 trunks, or does it solve some other purpose as well ?

2. when is the media path switched, is it in the the Active state only or could be in the alerting state as well. I guess progress indicator No 8 in the q.931 messages has something to do bout it?

3. if theres no media path established, and some remote exchange decides that some announcement needs to be played to the calling party, how is that done? is it through some control signal askin the local exchange to play the announement, or is it through media connection to some Intelligent peripheral, or some media packet going through the control channel.

thanks and regards,

B.S.Gill

Authorize_Call_Setup can be used for outgoing call screening and authorization. For example, some Centrex services require and prompt for a user id and accound code at this stage. > > 2. when is the media path switched, is it in the the Active state only > or could be in the alerting state as well.

All three are possible. The remote exchange can send "inband information available cut through in both directions" or the call can be diverted under SCF control to an IP, or the remote exchange can release with cause indicating an announcement number for the originating exchange to play. --brian > > thanks and regards, > > B.S.Gill > _________________________________________________________________ > > Do You Yahoo!? > [1]HotJobs, a Yahoo! service - Search Thousands of New Jobs > > References > > 1. http://rd.yahoo.com/careers/mailsig/new/*http://www.hotjobs.com -- Brian F.
