RSVP Bandwidth Calculations

RSVP bandwith calculations are based on worst-case scenario.  For G.729, this is 40 kbps.  For G.711, this is 96 kbps.

The ip rsvp bandwidth value should be equal to (x-1 calls at normal scenario + 1 call at worst case scenario).  For example, two G.729 calls would be calculated as 24 + 40 = 64 kbps.  In the example below, I have configured RSVP for one G.729 calls (1-1 calls at normal scenario + 1 call at worst-case scenario of 40 kbps)

G.729 with one 10-ms sample per frame
Bandwidth consumed: 40 kbps
Bandwidth consumed (cRTP): 9.6 kbps
Sample latency: 10 ms

G .711 with two 10-ms samples per frame
Bandwidth consumed: 96 kbps
Bandwidth consumed (cRTP): 80.8 kbps
Sample latency: 20 ms

Even though this call is running at 24 kbps, the RSVP algorithm will reject the call. RSVP sends an error message because there is not enough bandwidth configured for a worst-case scenario call.

Must-Know Quick Reference Guides

with 6 comments

First thing…  Set this URL to be your homepage from now until you pass your CCIE Voice lab.

http://www.cisco.com/cisco/web/psa/default.html

When you’re at work and have a problem, search this site for your answers.  Train yourself to use the documentation.  Resist the urge to use Google to find your answer.

The CCIE lab is just as much about knowing the technologies as it is knowing Cisco’s documentation.  How’s that for “drinking the Kool-aid” and taking the Cisco plunge? :)

These examples will provide you TONS of working configuration examples.  Be familiar with these guides.

CUE/VPIM Configuration

  • Clickable path: UNIFIED COMMUNICATIONS > UNIFIED COMMUNICATIONS APPLICATIONS > MESSAGING > CISCO UNITY EXPRESS > CONFIGURE > CONFIGURATION EXAMPLES AND TECHNOTES

  • Clickable path: CUSTOMER COLLABORATION > CONTACT CENTER > Cisco Unified Contact Center Express > INSTALL AND UPGRADE GUIDES > Cisco Unified Contact Center Express 7.0(1)
  • Cisco Guide: Cisco CAD Installation Guide for CAD 6.6 for Unified CM
  • Search for: “:62” – Third hit is what you need – Open in browser – Copy new link and values for One Button

You know there are two different URLs that can be used for the UCCX phone agent service?

One where you have to insert agent id, password and agent extension on the phone, since this takes valuable time away from your lab time we often choose to use the other method, namely the one where all this is already filled in when you subscribed to the service. In other words, the one button login.

There is a document that describes how to do this, but it can be somewhat difficult to find. At least if you compare to the effort needed to find the first example. But rest at ease, the is an easy way to do both with what you find in the easily found document.

The trick to find this second URL and the name of the parameters is to paste the first URL into a browser on your computer: http://<IP_of_UCCX_server>:6293/ipphone/jsp/sciphonexml/IPAgentInitial.jsp

In the result that comes up in your browser you will have the second URL and the exact name of the parameters needed, remember that these are case-sensitive.
