I have to design a VoIP solution for about 30 phones. 12 are in location A, 6 in location B, 5 in Location C, 2 in Location D and about 5 teleworkers (soft phone). The needs are presence and Video for sure. They also want to tie Webex with phones as they do a lot of meeting in conferencing.
Here's what I am thinking as a proposal.
UC560 at Location A - Use 4 Analog Lines and rest SIP trunks. Location B and C would be fed from here.
800 series in Location B and C - Create IPSEC VPN back to UC560. Use SIP trunks for DIDs and outgoing calls on UC560.
UC520 at Location D - Create IPSEC tunnel back to UC560 Use 2 analog lines (Since I cannot get DIDs for this location on SIP Trunks)
IP communicator for 5 remote users with anyconnect VPN.
Would this work? Would I hit any limitation on UC500 part here in regards to local area code or VPN or Dial-peer?
I am thinking of installing Smart Call connector (presence) as well.
I would appreciate any feedback on this.
