from a Cisco 2811.

It
is visible that there is no package with ACK confirmation
from a FreeSWITCH to
Asterisk. Asterisk sends several times
SIP OK on a freeswitch, and
without having waited confirmations (ACK)
after 23 seconds sends SIP BY on a freeswitch
and on IP Phone. After
that call stops. Before disconnection
subscribers hear each other of 29
(+-) seconds
In tcpdump
between Cisco and FreeSWITCH it
is visible that the SIP ACK packet
from Cisco arrives on a freeswitch.
In what
place the SIP ACK in a FreeSWITCH disappeared?
What to me to analyse in SIP session?
Maybe someone solved a similar problem?
please,
Help!
