<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I’m running Callmanager 5.1(2) and have a 2851 running
12.4(11)T3 with 2 FXO ports. When I reset one of the FXO ports from
callmanager it stays unregistered until I disable and re-enable mgcp on the
router. I took a packet capture, and when I issue the reset I see the
callmanager passing data to the router on the tcp/2428 backhaul connection,
which it looks like the router does not respond too. Sniffer decodes this
as a “MGMT_CHAN_RESET_REQ” message. “debug ccm-manager
backhaul packets” on the router does not show anything.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I thought the tcp backhaul connection was only used for
keepalives between the gateway and callmanager, and for carrying D-channel
information on PRIs so I am surprised to see anything being passed here when
there are only FXO ports on the gateway.<o:p></o:p></span></font></p>

and it stays registered on reset, and a packet capture shows normal mgcp packets,
and only keepalive traffic (no data) on the backhaul connection as I would
expect.<o:p></o:p></span></font></p>
