Memory recommendations and maximum numbers of IP phones are for common Cisco
SRST configurations only. Systems with large numbers of phones and complex
configurations may not work on all platforms and can require additional
memory or a higher performance platform. **
To get the same number of SIP IP phones support as SCCP IP Phones, SRST 4.1
in 12.4(15)T is required ***
Cisco Caalyst 6500 CMM supports Cisco Unified SRST 4.0
with Cisco IOS Release 12.4 and supports Cisco Unified SRST 2.1 with Cisco
IOS Release 12.2(13)ZC. |
