We have the need for some small branch offices that will requre voice communication to our main branch.
We have Cisco Call Manager at the main office that currently services several branches.
I would like to use the 1861 series router, but I ma not sure which one will do what is needed.
According to the documentation:
"â¢ Integrated Cisco Unified Communications Manager Express or Cisco Unified Survivable Remote Site Telephony (SRST) for call processing"
This should be all that is needed correct?
