RE: www1 and www3 working paralell? |
|
The www3 server is still down, but www1 was not affected at all by this connectivity issue.
To minimize downtime in cases like this, the recommended strategy is to setup another PBXes account, host it on another server (like www1 in your case), and duplicate the setup you have on your primary account.
All your SIP User Agents should register an extension to both servers, and in case of failure you just route calls over the functioning extension.
This works without any issues for outbound calls, but leaves inbound calls from most ITSPs to end up going to the failed server for period of time. That situation creates an issue, until the trunks on the working server take over the registration.
Which brings us to the topic of concurrent registrations. Some ITSPs will gladly allow you to register from multiple SIP UAs located in different places for free, some will try get additional funds for the privilege (e.g. Broadvoice), while other ITSPs won't touch the subject with a ten-foot pole.
Concurrent registrations allow our DIDs to support fail-over, which is their most important feature, since we need to be able to answer incoming calls at all times. So we need to demand that ITSPs allow concurrent registrations, and make it an issue when they refuse to. Otherwise forget automated fail-over for inbound calls.
