[SIPForum-discussion] capability query and Invitation procedure

[sipsipsip sip]

Hi all,


             I need some clarification on capability query and Invitation
procedure

The Reason why we use capability query is that

To query for terminal capabilities (endpoint is capable to support certain
media features?).

Why this cant be done using Invite procedure ??
It can be done using the SDP paramters and negotiations can be done . Why to
use capability query

Regards,
John
