Hello EE,

I talked to Cisco and a couple resellers who both tell me that I need one or the other, but nobody can tell me the real difference and I'm having a hard time in searching on it.  Any help would be great.  We have a site that is moving to Cisco Voice and we need to replace the router so I am given these two options.  What are the differences?  Pros/cons?

ok its like this:

C2921-CME-SRST/K9 is the following:

Cisco 2921 voice bundle with packet voice DSP module (PVDM3-32), FL-CME-SRST-25 - Feature License for 25 CME/SRST users, and Unified Communications (UC) License PAK

C2921-VSEC/K9 is the following:
Cisco 2921 Voice Sec. Bundle, PVDM3-32, UC and SEC License PAK

Both are 2921 routers, both of PVDM3-32 DSPs, the CME-SRST has the CME/SRST 25 users license if you are doing Callmanager Express and need up to 25 phones or if you are using this router as a fallback in case connectivity to call manager is lost and you need SRST - Survivable Remote Site Telephony.

If you this is just a voice gateway to terminate some PSTN and there is no requirement to run CME or SRST go with the VSEC model.   If you want call fallback functionality at a branch go with the CME-SRST model.

The boxes are identical - its just a CME/SRST license comes with the first unit.  You can always add it to the 2nd unit.

Is it cheaper to do it one way v.s. the other.
I need 50 SRST so one is adding 25 as the router comes with 25 where the other is adding 50 to the VSEC/K9

well the pricing is done by the cisco reseller.. If you need 50 SRST the pricing is going to come out pretty close between the two if not the same.  Cisco simply created some bundles to make ordering stuff easier.   Ask your reseller to quote you both ways and see what they come back with.  Most likely it will be the same.  The only difference might be in the smartnet services.  Maybe..
