SMS service SIP also provides a variety of forms for a variety of SMS. Because SIP can process all transmissions in a single session, instant information (IM) and SIP binding applications are much more effective than combined with WAP.

IM can make users send personal information to selected people during the call, and join the SIP function means a huge profit market is in front of them. Real-time location-based business image conference call This is not one of the main business of SIP, but such sessions are not limited to voice and videos, but are not limited to wireless networks.
