Reliable applicance for routing IT emergency calls (SIP and ISDN)
- by chiborg
We have a fairly big IT installation and our IT staff needs to be reachable 24/7. At the moment we have the following setup for "emergency" calls to our IT staff on our main Asterisk box:
An incoming emergency number (connected via SIP trunk and a BRI card
in case the SIP trunk goes down).
When the number is called during the office hours, all the SIP phones of the IT staff are called
simultaneously.
When the number is called out of office hours
interface, a list of mobile phone numbers is called, one after
another until someone picks up.
The list can be changed by the IT
staff via command line script.
The setup works well, but the Asterisk is heavily used in a call center, has experienced some outages and misconfigurations, each of them bringing down the IT emergency number. So we'd like to put the IT emergency call functionality on a separate device. This does not need to be a big server, it even does not need to be Asterisk, it only has one purpose and should do it reliably. It should be very low-maintenance. Any suggestions for hard- and software?
