Ok as you say it realiable transport ensures delivery of messages to other end, then why should we start timer B?

Hi Banu, 
    In case of un-reliable transport, as you know that there are chances of dropping sip message on network. Because of that SIP ensures that if a UAC won't get response in a certain period of time it would retransmit the message. Because transport is not ensuring the packet delivery so SIP takes this responsibility and ensures deliver a message on other end. But in case of reliable transport, transport ensures delivery of sip message on other end and takes care of any data loss. So there is no need to start timer to re-transmit data as it is ensured by transport layer. 
  
is what i understand.

In case of reliable transport, why timer A is not set to fire.. i.e
retransmission timer,
Only timer B is set.
