SIP HOLD: A Way for Passing INVITE when putting call on HOLD


Currently, Asterisk is behaving as follows:

scenario: endpoint A, which is registered with Asterisk, is in a SIP call with endpoint B, which is also registered with Asterisk. endpoint A and B are SIP phones. When A presses HOLD, the following takes place:

-SIP signalling takes place between A and Asterisk (B does not get involved in the SIP signalling).

-A sends INVITE to Asterisk. Asterisk sends OK back.

-B hears music on hold.

My question: Is there a way to make Asterisk pass the HOLD INVITE to B so that B is involved in the HOLD SIP signalling?

Thank you for your help
