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.
There is no hard disk in ISM-SRE-300-K9. Only 4-GB internal USB flash-memory module is there. If we require more space for voice mail should we go for SM-SRE-700-K9?? What actually 4-GB internal USB memory will keep in ISM-SRE-300-K9? CUE, AA, Voice mail all these possible to keep in 4-GB?
