[SIPForum-discussion] Difference between Path and Service-route header fields

[anuj]

Hello!There are two optional fields of the SIP header \"Path\" and \"Service-route\".From their usage i could see that both are used for populating the route header fields and are inserted by the proxys to forcethe routing of future messages during registration through them.Only difference i could notice is that the Service-rout is added only in 200 ok response!!!I want to know if i am correct or ther are other difference as well?Also Whether this forced routing is only for the messages flowing during registration or for all the messages which follow even after registration?thanks in advance!anuj
