* 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. **** SRST 880 is natively supported by CUCM 6.13 and 7.1. |
