Cisco UMG 8.6.1 and Cisco SRST 8.8 or 9.0 compatibility?

Hi!

We have a customer who'd like to deploy 600 phones (3905) at their remote office. I can see that for classic SRST the max capacity for 3945 router is limited to 350 phones which is not enough in the current situation but for E-SRST the number is 1200. As it is know Cisco UMG is needed for deploying E-SRST. However the 3905 phone is supported starting with CME/SRST version 8.8. The latest version for Cisco UMG is 8.6.1 and I can't find any info about its compatibility with CME/SRST 8.8 or higher. Could somebody help me out and clear the situation? If it is not compatible then we'll have to persuade or customer to buy two 3945s.

Thanks!

Where do you see that only 350 phones are supported for SRST? It is 1200:

350 is for CME not SRST.

HTH,

Thank you, Chris!

I've read this document a couple of times:

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6788/vcallcon/ps2169/data_sheet_c78-678873.html

And everytime I read it I somehow thought that the column for E-SRST is actually for SRST - hence my confusion. You've saved my day!

Thanks again!
