[SIPForum-discussion] Call Hold

[Ravi Siebel]

Hi All,
   
  Suppose there is SIP session established between 2 SIP UA ('A' & 'B).
   
  Now 'A' put 'B' on Hold by sending REINVITE with sendonly.
   
  1) Please let me know , it is follow the latest standard of RFC 
   
  2) In case only direction RTP stops or both ?
   
  3) In this if the internediate server(proxy server) is down during put on hold condition, user will re-transmit re-INVITE till 31 sec. In this case wht is the status of the call from both end.
   
  4) When user 'A' put on hold by sending INVITE , does he stop sending the RTP packet parallely to the sending re-INVITE
   
  Thanks in Advance
  Ravi
