Subject: [OSL | CCIE_Voice] MGCP Gateway reg issue (not l2 TEI or l3 bind)
To: <ccie_voice@onlinestudylist.com>
Dear all,
thanks for all of the suggestions.
I have removed the gateway from CM and restarted the Pub abd Sub servers
from the CLI (utils system restart)
I removed the mgcp bind media and control from the loopback interface and
reloaded the BR1_RTR (after saving). This results in the gateway binding to
the 1st BR1 serial int 10.10.111.2.
I am curious as to why the logs show that the mgcp tries to bin to the full
PRI even though the pri-group specifies that it should only bind to channels
1-6 fro mgcp.
Does the 2651xm router support fractional pri bind for mgcp?
Here is the config
BR1-RTR(config)#do sh run
