We've seen similar with Netscreen devices. In my case it was
performing stateful blocking - i.e. only blocking the MGCP DLCX
messages. Firewall troubleshooting should be taught as a 4000 level
course from application perspective.<br>

Had a problem with Checkpoint recently. It tried to do it's deep
inspection on MGCP, allowed the TCP 2428, but the UDP was dropped.<br>
To make it more interesting it was dropped silently and didnt appear in
any CP logs :)<br>
<br>
If it is CP let me know.. I have the solution id's with the versions
affected and fixes.<br>

depends on TFTP.<br>
you will use RTP.<br>
<br>
unless using security features you will not be using esp/ike/sRTP<br>

are you using 'ccm-manager config'?<br>
are you using encrypted signaling or sRTP?<br>
are you using RTP?

This is for a CM 4.2 site, and per here:<br>

I see ports 2427 UDP and 2428 TCP listed for an MGCP gateway. Do I<br>
also need to QoS the ESP, IKE, TFTP, RTP, and SRTP ports as well when<br>
utilizing MGCP? Am i missing anything else?<br>
<br>
Thanks,<br>
<br>
