I have an SM-SRE-700 voice module. Can I install this module in a Cisco 2911 router? The SM-SRE-700 voice module was pulled from a Cisco 2911 at my job that was not being used. I have a test network with working Cisco phones running on the 2911. I want to try to configure voice mail on my test network .
Yes, that module will go into a Cisco 2911 router. (If it came out of one, it stands to reason it would go into another.)
Are you hoping to install Unity Connection on it? I know you can install Unity Connection in SRSV mode on that module. It also supports Cisco Unity Express. I don't know if you can install full Unity Connection, though.
I have one 2911 with SM-SRE-700 in my lab.. You can use SM-SRE-700 on 2911 and configure unity express up to 8.6. Unity express 9 and 10 are virtual and not supported on SM-SRE-700.
For unity express virtual you you need Cisco UCS/Cisco UCS E-Series Platforms. Unity express 9 and 10 are EOS and the replacement will be unity connection. Unity connection can be installed on Cisco UCS/Cisco UCS E-Series
So better make use of unity connection if you need to test voicemail as the setup you are trying is quite old method.
