+===== CUCM Configuration =====
+  - Create dedicated Partition for customer
+  - Add customer parition to "Incoming_b2b" Calling Search Space
+  - Create dedicate Location for each customer assign to SIP trunk
+  - SIP trunk to CSD-001 and CSD-002 for SIP adjacency to the SBC, assign it the Customer dedicated location
+  - Create a dedicate Route Group for each customer, add the two customer adjacency SIP trunks to the route group and make CSD-002 the primary
+  - Create a dedicate Route List for each customer, add the customer Route Group to the Route List
+  - Create Route Pattern to Customer Numbering Range, put that into the customer partition

+===== Cisco Troubleshooting =====
+==== B2B - Basic troubleshooting for TelePresence B2B Calls ====
+TelePresence endpoints are single and three-screen endpoints that are SIP standardsbased. Most of the B2B calls are routed through the Cisco SBC ASR platforms.
+When there are problems placing B2B calls, there are a number of steps that you can take to isolate the cause of the problem.
+{{tp_b2b.png|}}
+To troubleshoot a B2B call, do the following procedure:
+=== Troubleshooting within your network ===
+  - All rooms are failing to place B2B calls or only 1?
+    * Verify CTS version is compatible with remote equipment
+  - Is this room enabled to place B2B calls?
+  - Do you have security enabled in the CTS/Tandberg endpoint?
+  - Do you have a valid route pattern and Calling Search Space access from your room to the remote B2B number?
+  - Is routing properly setup between your Company and the remote SBC for Company B or TelePresence Exchange?
+  - Is there a Firewall, CUBE, ASA or any other device in the middle which may be preventing communication between your Company and the remote SBC?
+  - Have you collected CTS, CUCM and SBC logs?
+If you need to troubleshoot video and/or audio quality issues for any call for which the call passes through the SBC, it is easy to get some good information/statistics vlia CLI. Note that there is no easy way  to programmatically identify dbe media-flows correlating to the sbe call leg based on calling/called numbers since the sbe/dbe do not use the same keys/contexts. Still, you can usually identify the media-flow of interest if you know the media-address on the Customer’s side. Some basic commands are below.
+For dialout calls placed on enterprise endpoints, check the status of the call on the session border controller (SBC).

+=== Commands and debugs (ASR platform) ===
+The following commands can give you valuable information to verify call information.
+**show sbc <your sbc name> sbe adjacencies**
+**show sbc <your sbc name> dbe media-flow-stats summary**
+**show sbc <your sbc name> dbe media-flow-stats detail**
+**show sbc <your sbc name> sbe calls**
+**show platform hardware qfp active feature sbc  pfilter global**
+**show ip socket detail**
+**show sbc <your sbc name> sbe sip statistics**
+**show sbc <your sbc name> dbe forwarder-stat**
+**To collect logs in SBC ASR:**
+  * sbc dump-diagnostics harddisk: (issue once to clear the log)
+**debug sbc <sbc-name> log-level console 0**
+**debug sbc <sbc-name> log-level buffer 0**
+  * Place the call
+**sbc dump-diagnostics harddisk:** (dump the log for this new call)
+Collect ipstrc and pdtrc file from harddisk.
+  * After test is complete, you can optionally reset the debug levels:
+**debug sbc <sbc_name> log-level console 63**
+**debug sbc <sbc_name> log-level buffer 63**
