It appears the hangup is triggered by a SIP ACK with CSeq set to 0.
Some Grandstream UAs happen to pick 0 as CSeq. chan_sip.c contains
if (!p->lastinvite && !strlen(p->randdata))
p->needdestroy = 1;
where p->lastinvite hold the matching CSeq from the last INVITE.
0 in this case...
Fixing this does bring downs the number of hangups, but does not
entirely solve the problem. We are still looking.
