Resolving Bearer Channel Connection Problems
If the system is properly configured to use a dial plan, the system returns a response like the following:
MGC-01 - Media Gateway Controller 2001-06-01 10:09:47

"session=active:sigsvcprop"

Step 3 If your settings for the highlighted properties match what is displayed, proceed to Step 6. Otherwise, you
must modify the COT settings on the Cisco PGW 2200 Softswitch. To begin modifying the COT settings,
start a provisioning session as described in the “Starting a Provisioning Session” section on page 3-64.
Step 4 Enter the prov-ed: component :name=" comp_name ", cot_prop = value,cot_prop = value,... command to
modify the COT settings on the Cisco PGW 2200 Softswitch.
Where:
• component—MML component type name for the SS7 signaling service or trunk group properties.
Enter one of the following:
– ss7path—Component type for SS7 signaling services.
– trnkgrp—Component type for trunk groups.
• comp_name—MML name for the affected SS7 signaling service or trunk group.
• cot_prop—Name of the COT property you want to modify.
• value—Value for the specified COT property.
Step 5 Save and activate your changes according to the instructions in the “Saving and Activating your
Provisioning Changes” section on page 3-65.
Step 6 Debug the COT settings on the associated media gateway using the show cot dsp, show cot request,
show cot summary, and debug cot detail commands. See the documentation for the associated media
gateway for more information on these commands.
If debugging the COT settings on the media gateway does not reveal any problems, or does not fix the
COT failure, proceed to Step 7.
Step 7 Contact the Cisco TAC to analyze the problem further and to determine a solution. For more information
about contacting the Cisco TAC, see the “Obtaining Documentation and Submitting a Service Request”
section on page xviii.
