===== 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).
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.

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.
=== Commands and debugs (ASR platform) ===
The following commands can give you valuable information to verify call information.
**show sbc sbe adjacencies**
**show sbc dbe media-flow-stats summary**
**show sbc dbe media-flow-stats detail**
**show sbc sbe calls**
**show platform hardware qfp active feature sbc pfilter global**
**show ip socket detail**
**show sbc sbe sip statistics**
**show sbc dbe forwarder-stat**
**To collect logs in SBC ASR:**
* sbc dump-diagnostics harddisk: (issue once to clear the log)
**debug sbc log-level console 0**
**debug sbc 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 log-level console 63**
**debug sbc log-level buffer 63**

Packet drops can happen for a number of different reasons (layer 1 – 7, osi). Item 1 & item 2 allow you to track drops at the sbc software level (Layer 5+). To track lower layer problems (for example, drops caused by rtp packets that have udp checksum errors), use command 3 from below (only an example to give you an idea of the commands used, you can use different options to suit your needs).
