Hi Aman,
Thanks for reply.... :)
u said for 1st case i.e for connection field 400 is correct but i hope
606 also a proper response because of the following statement in RFC 3261
*"301 Incompatible network address formats: One or more network address
formats contained in the session description are not available."*
As connection fiels indicates* network address formats *only rite???
am i correct???
Thanks
Manjunath
