Hello
I have a VPN connection between the headquarter (there is one Cisco2821-sec/k9) and 3 agency (there is on Cisco 2801-hsec/k9 on each agency)
I have also one UC-560 installed at headquarters with IP-Phone SPA-504G for VoIP call
They are plan to install many IP-Phone SPA-502G on each agency and make call with headquarter
Is it possible for users (12) in the Agency to make calls with other user in the same agency if the link with the the headquarter goes down ?
What do I need to perform it.

Two quick feedbacks for things of concern here.
SPA phones are not supported on ISR, only UC5xx.
Uc5xx doesn't support SRST or integration with ISR.

Thanks for your answer
I have a VPN connection between the headquarter (there is one Cisco2821-sec/k9) and 3 agency (there is one Cisco 2801-hsec/k9 on each agency). the VPN is working fine
So if the UC-560 don’t support SRST, I need to move to call manager
The vpn link bandwidth between each agency and the headquarter is 3 Mbps
The call manager should be at the headquarter, the headquarter should have 30 ip phone
There is 4 PSTN line at the headquarter
Each agency should have 15 ip phones
each agency have 2 PSTN line, these 2 PSTN line should be connected on the router (Cisco 2801-hsec/k9). normally, we must add FXO card
It should be possible for the user on each agency to call each other if the link with the headquarter is down. The user on each agency should be also able to call or receive call through the 2 PSTN line when the link to the headquarter is UP or down
please some could you help me to choose built the new network ?
what are the reference list of equipment that I need : (call manager, router, IOS, ip phone ...).
Please help

What you are looking for is a bit more invovled where a forum post would not answer all your questions. For starters you can refer to the CUCM SRND guide-
Unified Communications Deployment Models
http://www.cisco.com/en/US/partner/docs/voice_ip_comm/cucm/srnd/8x/models.html
It would be best to contact a partner or your Cisco Rep where they can assess your business needs and properly recommend the hw/sw and dial plan considerations.

Hi
Thanks for your answer
see below the order option that I choose for 100 users
Part number | quantity | Description |
MCS7828I4-K9-WL | 2 | CUCMBE, 7828-I4 appliance, CUWL BE 50 Users |
CMBE-WRKSP-BDL | 1 |
|
Is it OK ?
Do I need to but another router for voice at the central site (see architecture) or I can use the actual Cisco2821-sec/k9 using for VPN ?
If I can use the Cisco2821-sec/k9 for voice, what is the IOS oder part number option that I should buy ?
What is the order part number that I need to buy to add on each Cisco 2801-hsec/k9 at the agency to have voice and SRST ?
Thanks for your help.

For any UCM related questions you might be better off posting a thread in the "IP Telephony" forum-
https://supportforums.cisco.com/community/netpro/collaboration-voice-video/ip-telephony
If this is your first time doing a deployment of this size if may be best to engage a partner or a Cisco rep to align you with the right contacts.
