I have a Cisco 2651XM router and I want to start playing with ip phones and learning about voip telephone systems. What software do I need that will be compatible with my router to get me started? I have the c2600-ipvoicek9-mz.124-4.T1.bin IOS so I expect I'll have to load that. I've read about Cisco unified communications and also Cisco Call manager but don't know if this is compatible with my router or whether I need an earlier version. I'm also going to buy 2 or 3 cisco ip phones and I'd appreciate advice as to what models I should go for, based on my router and IOS. Thanks for any pointers.
CUCM not compatible as it needs MCS server, but you can have a CUCME on that router
you can only go as far as 4.1 version with that router model you have
you can check compatibility on this link:
Cisco Unified CME and Cisco IOS Software Version Compatibility Matrix
config can be found here:
Cisco Unified Communications Manager Express System Administrator Guide
