Hi,

A UA that supports session-timer establishes a call with another UA that
supports session-timer and the refresher is, say, uac. The UAC, sends a
re-INVITE to hold media. If the re-INVITE contains Supported: and
Session-Expires: headers, it may be mistaken for session refresh. Should the
UAC send re-INVITE without these headers to hold media? A re-INVITE having
both Supported: and Session-Expires: headers and increased version in o=
line of SDP (for both timer refresh and hold) is allowed (hold and session
timer referesh allowed in a single request)?

Thanks in advance.

Warm regards,
