[SIPForum-discussion] response of a invite depends on which header

[VG]

Hi,

I like to know on which parameter response of INVITE as well as other
request is dependent.
Like there are 3 things comes into the picture:
1) via
2) contact
3) record-route.
What is the priory of these header.
Which one is given first preference if present all.

Thanks in advanced.

Regards,
VG.
