Are analog phones counted as phones from an SRST perspective? The analog phones will be behind a 2851 (off VG224's). The VG224's will be setup with MGCP and failover to h.323 (with a dial-peer 9.T) pointing to the SRST router (2851). My scenario will have 70 ip phones or so. The hope is I don't have to go up to the 3800 series in order to get all the analog phones licensed for SRST.
You won't love this info, but I'm sure it applies to the VG224 as well :(
During Cisco CallManager fallback, Cisco SRST considers the Cisco VG248 to be a group of Cisco IP phones. Each of the 48 ports on the Cisco VG248 is treated by Cisco SRST as a separate Cisco IP phone.
Hope this helps!
