* 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.
** The Maximum
Total IP Phones can be split between SCCP and SIP phones as long as the
maximum total of IP phones are reached. *** Cisco Catalyst 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. **** SRST 880 is natively supported by
CUCM 6.13 and 7.1. To get the same number of SIP IP phones
support as SCCP IP Phones, SRST 4.1 in 12.4(15)T is required. |
