I have a C2901-VSEC-CUBE/K9 router that would like to set up as an UC lab. I would like to run CUE for voicemail and AA. The only way I can run CUE is if I install a service module like the ISM-SRE-300-K9? I was wondering if I could run CUE with the Embedded Service Engine and internal router memory.
It does makes sense since I would need extra memory/disk space for the voice messages etc.
You need one of the following modules:
SM-SRE-700-K9, SM-SRE-710-K9, SM-SRE-900-K9, SM-SRE-910-K9, ISM-SRE-300-K9 and NME-CUE with SM-SM-ADPTR
for 29XX routers per data sheet:
There is no way to run it without any of the above.
