Nevermind, I have solved the problem.

Subject: [Asterisk-Users] MGCP : chan_mgcp.c:1509 find_subchannel
Importance: High

When I try to connect to * using a Cisco ATA 188 configured with a MGPC firmware (v3.1.1), I just
keep getting this message every 30 seconds or so :

May 10 10:08:21 NOTICE[7913]: chan_mgcp.c:1509 find_subchannel: Gateway '192.168.1.27' (and thus its
endpoint '*') does not exist

Using tcpdump, I have checked that the ATA188 (with IP 192.168.1.27 and port 2427) sends UDP packets
to * (IP 192.168.1.59, port 2727). On the other hand, after sending 2 packets at startup, * does not
respond to the ATA188.

This certainly looks like a configuration problem, but I just can't seem to find exactly what is
wrong. If someone has experienced the same problem or know what is wrong then I would really
appreciate your help.

Thanks,

JF
