Description:	This issue happens with chan_sip. Given I have two SIP users Alice and Bob Given Alice calls Asterisk Given Asterisk calls Bob and bridges him with Alice in a direct media bridge When Alice sends a re-INVITE, with the final ACK request containing a SDP with a new connection address Then Asterisk does not send a re-INVITE to Bob with the new connection address Expected : Asterisk sends a re-INVITE to Bob with the new connection address To be clearer, here is a sequence diagram : ||Alice||  ||Asterisk||  ||Bob|| | |INVITE (SDP : c=@addrA1) --->|  |  |  | | | <--- 100/180 |  |INVITE --->|  | | |<--- 200|  | <--- 200 (SDP: c=@addrB1) |  | | |<--- INVITE (SDP: c=@addrB1)| *direct media establishement* |INVITE (SDP: c=@addrA1) --->|  | | |200 --->|  |<--- 200  |  | | |INVITE --->|  |  |  | | | <--- 200 |  |  |  | | |ACK (SDP: c=@addrA2) --->|  |  |  | At this point Asterisk should send a re-INVITE to Bob with @addrA2.
