I would like to return this old thread about dsm
B2B.otherBye/B2B.sendReinvite. According to dsm_syntax.txt:
B2B.sendReinvite(generate_sdp [, string extra_headers])
send a reinvite in caller leg (first leg), e.g. to
reconnect first leg after B2B.otherBye received.
generate_sdp can be 'true' or 'false'
(B2B.sendReinvite(true) recommended)
The problem is that B2B.otherBye() event has already already terminated
the whole call and it is too late to call B2B.sendReinvite() in
B2B.otherBye() transition.
In the test I have
transition "bye on other leg" conn - B2B.otherBye() / {
log(2, received bye from callee);
B2B.sendReinvite(true);
} -> thanks_for_calling;
and I get to syslog:

How to prevent B2B.otherBye() event from terminating the call? Is there
some magic missing from the above B2B.sendReinvite description?
It would be nice to get this solved before 1.7 is out. The whole test
diag is below.
