Hello Andreas,

At SipIT 13 in Ottawa method #2 was discussed as the preferred mechanism.

Regards,
Mark

Subject: [Sip-implementors] Call hold questions


I'm a bit confused regarding Call Hold service using SIP. I have seen two
differnet approaches to solve this:

1. Send a re-Invite with "0.0.0.0" as the IP address in the sdp data
2. Send a re-Invite with the parameter a=sendonly set in the sdp data

Is there some draft or RFC about this? Which one is preferred? I guess it
is
best to have support for both ways (at least receiveng call hold) but when
I
send the call hold I need to know which way to use.

Do you see any pros/cons about the two different solutions?

Regards,
Andreas
