What is the difference between IAM and SAM?..

Answer / sri

IAM -- Initial address message i.e. this is the first packet
which contains calling party, called party address etc.

SAM -- subsequent Address message i.e. if the IAM length is
more than the max allowed on the network i.e 272 octates,
then the IAM will be fragmented to multiple messages, the
first one will be IAM and the subsequent messages will be SAM

Answer / abhishek tyagi

No if IAM is more that 272 octect it will be fragmented but
name of that message is segmentation. SAM is used for
overlap calls. When user dials some digits and SS7 node can
find the next hop without receiving all the digits from
user, in this case ss7 will send the IAM with those digits
and other dialled digits will be sent in SAM.

Answer / abhishek byahut

IAM(Initial Address Message)contains the information
requried for setup call.For a basic call it is a first
message send to Destination.
SAM(subsequent address message)exactly it is overlap calls
address.
SAM message has to be sent in the scenario when suppose a
subscriber dialed a number 9321353536.
SSP send the IAM message to there destination without
reading the 353536. I.e originating SSP looks 9321 and
sends the IAM message to their respective Destination.
And SAM to be send with rest dialed digit.
