I have got some doubts :
Suppose a Hutech no dial an Airtel no and the Airtel Subscriber is switched off then :
01} Will the announcement of “Swicthed Off” be played by Airtel exchange or by Hutch Exchange only .
02) Whether any kind of Voice Trunk Seizure happens in any of the 2 scenario -announcement being played by Orginitaing Hutch or the Terminating Airtel.
03) IF at all some kind of voice trunk seizure does happen then what exactly is the parameter in the SS7 which ensures that there is no charging for this particluar seizure
03)Also if there are some fixed scenarios in which the Announcement is played by the “B” party exchange (like the Subscriber Busy)& some scenarios in which the Announcement is played by the “A” party exchange.I would like to know in the following scenarios :
“B” part no not recahable
“B” party switched off
and alos whether in all these scenarios Trunk Seizure happens
04) For “A” party EXchnage only playing announcemnet is there some special TG used for the Announcement Playing
