Don't miss important calls! Our Failover Service allows you to provide us with alternative delivery phone numbers and/or Backup PBXs in the event that we can't deliver a call to you.

If you do not have failover service set up, we try to send your calls to you from trunk1.freepbx.com. If you are not registered, or the attempt otherwise fails to reach your PBX, we then try sending the call to your from trunk2.freepbx.com. If that doesn't work, we give up.

Failover can prevent this from happening. If you set up an alternative phone number and/or backup PBX as a failover option, this will give us another way to deliver your call.  With the failover service outlined below, you are provided with a wide selection of options

 The most commonly used option is an alternative phone number to reach you if the call fails. You can provide a different phone number for each DID that you own, as well as a single "global failover" phone number for the whole Trunk Group. Upon a failure to deliver your call, we will check if your DID has a failover number configured. If so, we will send the call there. If the DID called does not have its own failover number configured, we will check if the Trunk Group has a global failover number configured. If so, we will send the call to that number.

In addition to a failover number, you can define a failover PBX to send the call to by providing either an IP address, FQDN or if you have more than 1 Trunk Group Setup you can pick a different Trunk Group where we can send the call. This is done at a Trunk Group global level.  With this configuration, if you are not registered or the attempt otherwise fails to reach your registered PBX, we will try to send the call to this alternative PBX address. 

If you configure both an IP address or secondary Trunk Group and a failover number, then we will first try to route the call to the alternative PBX, and if unsuccessful, we will then send the call to the alternative phone number.

Common Setups for Failover

Log into the SIPStation Store and then follow the instructions below, depending upon whether you are setting up a global failover or per-DID failover.


Setting a Global Failover


Setting a Per-DID Failover

How to Set Up Failovers from the FreePBX SIPSTATION Module

Now that you have set a global failover number, you can optionally set failover numbers for individual SIPStation DIDs. If you do not set failover numbers for any DIDs, and we cannot deliver your call, we will look to the global failover number set above. If the DID has its own failover number, we will use that instead of the global number.


Important Detail when using Failover Services:

We previously described that in most circumstances, we try to deliver calls from trunk1.freepbx.com, and if you are not registered, we will have trunk2.freepbx.com try to deliver your calls. For any DID that has failover services configured either at the per-DID level or the account level, our trunking server that first tries to deliver the call to you will NOT pass the call on to our other trunking server if it can't reach you. Instead, it will use whichever failover configuration you have setup. This means that it is important for you to dual-register with us, so that regardless of which trunking server is trying to send you the call, we will only fall back to these failover services IF your server is not available.
