H323 Gateway (ISR 4321) Maximum call blocking using rejection rule

[jrdiaz]

Hello Everyone,

Good Day. Is there any document stating the maximum number of call blocking we can do on a H323 gateway (ISR 4321)? Also is the "Route Next Hop by calling Party Number" can be used as call blocking after reaching the call blocking limit of h323 gateway?

Thanks you so much :)

Voice translation-rule configuration

Command History

Release	Modification
12.2(11)T	This command was introduced with a new syntax in voice-translation-rule configuration mode.
15.1(4)M	This command was introduced with an increase in the maximum value of the precidence variable from 15 to 100.

2) Yes You can use the Route Next Hop By Calling Number , If the Call is not blocked by the voice translation rule then you have to route it to CUCM. There is not upper cap on Number of Translation rule in CUCM but it depend on resources available.

A better approach will be to use CUCM it self as it will give higher limitations.
