[asterisk-users] Small site survivability

Audiocodes supports SRST on their mediapack analog gateways.


This might be a viable option.  I haven't used any Audiocodes devices
before.  Are people pleased with them?

We do not want to decentralise our configuration.  The whole point of
pulling all of these sites together was to centralise management.  We also
have a lot of users that move to a different site every year and keep their
DID as long as they are within the same county.  We simply need some way to
provide basic call management for local 911 access in the case of WAN
failure.  Our Cisco devices do this for any phone using SCCP.  If you want
to buy an additional license you can have SIP too...

I work in K-12 education, so while our users will complain that they don't
have internet/email/etc, they continue to work with or without the WAN
connection.  Even if normal phone service is not available, we HAVE to
provide 911 access.

I am trying to avoid adding additional servers at this small sites.  Some
sites are nothing more than a portable with Metro Ethernet connection and a
fan-less router and switch.

Backup WAN links... I wish!

Thanks for the input.
