Re: Number of Srst References in centralized call processing

Hello Ahmed,

 

I think it should be same as how many gateways you can add in a cluster.

Because you will configure the SRST config on gateway/routers only and it should be same in numbers as your gateways.

 

Thanks

Re: Number of Srst References in centralized call processing

There is no limit defined as per the documentation on Number of SRST Reference OR number of Device Pools. Only Limitation I can see is Location and Region and Gateway. So Theoretically speaking no limit is defined. As Region Location Device Pool and SRST Reference are all tied we can take those values as reference.

SRND Says
"Configuration of regions and locations in the Unified CM cluster requires both database and static
memory. The number of gateways that can be defined in the cluster is also tied to the number of locations
that can be defined "

Re: Number of Srst References in centralized call processing

I find this document

The centralized design consists of a headquarters site and up to 49 remote sites.
Can you explain this please ?
Is it mean that remote site = SRST Reference ?

Hello Ahmed,

 

I think this guide is specific to BE6000 server and explain what you can support using this server.

But in general no limit is mentioned in SRND.

 

Thanks
