it signify that the session will be avaliable during the time interval
between "5" and " 6" .

 

Actually,  the value for the <start time> and <end time> should be the
decimal representation fo NTP time value in seconds.

 

for more refer RFC2327 page-15 para-2

		Thank u srnivas

		 

		Suppose T = 5  6

		 

		This indicates what??

		 

		What is meaning of session is permanent.

		[DG] A permanent session does not expire but it end with
a related BYE

		 

		( when ever we are having either AUDIO or VIDEO session
, then it persisit for some time ( let 5 hrs) . can we call this type of
session as permanent session 

		[DG] Yes, i think this kind of session is a permanent
session

		 

		Plz give an example of permanent session

		'T' line specifies the duration of the time for which
the session is active.

		If both stop and start time is 0 then session is treated
as permanent.

		 

		For more info Refer RFC 4566 section 5.9

		T= <start time> <stoptime >

		 

		Generally in the example it is indicated as T= 0 ,0
