> 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.
