Pls. explain how SIP is advantages than ISUP sajit4134 07-July-2008 04:33:58 AMComments Some advantages are SIP works independently of the type of session, or the media used, giving it flexibility. It is an open standard, allowing multivendor support and integration. Applications can be written to customize SIP uses. SIP messages are clear text, making troubleshooting easier. SIP can accommodate multiple users with differing capabilities. For instance, in a conference that has some users with video capability and some only with audio capability, the video users can see each other. They do not have to drop down to audio only, as with other protocols. Posted by HamidAliKhan SIP : - Simple, Scalable and Extensible - Requires about four packets for call-setup - Cannot provide - Minimal capability exchange, enough for IP telephony - Not required for SIP multicast conferences - Basically runs on UDP. Reliability achieved through retransmissions. Supports TCP also, if UDP is not supported - Easy to implement SIP Pros * SIP works independently of the type of session, or the media used, giving it flexibility. * It is an open standard, allowing multivendor support and integration.
