Why Set an Alternative Routing to Your SIPTrunks?
Setting this will help your phone system to stay functional in the event of a internet outage that prevents your bvoip phone system from working. A common example is that of a system reboot. When a system reboot occurs, the alternative routing will take effect, preventing any missed calls.
Option One: PSTN Backup
Why Use This Option? PSTN BU works just like a hard forward but is ONLY triggered when SIPTrunk.com receives no response from your server or you do not have an active registration on your trunk.
- Login to your SIPTrunk.com portal.
- Navigate to the DIDs tab.
- Scroll down to the desired DID.
- Click on the pencil button next to the DID to edit it.
- In the PSTN BU field, place the phone number you would like the calls to forward to. Note: Make sure to include the 1 prefix to the number.
- Click on the Submit button.
Rate Plan Warning
If your sip trunk is using a channel-based rate plan with unlimited minutes, the forward will use 2 channels. One for inbound and one for the outbound. If you do not have at least two channels on your sip trunk, this option will not work.
Option Two: Voicemail to Email
Why Use This Option? As with PSTN BU, this option will only kick in if SIPTrunk.com do not get a response from your server or there is no active registration on your trunk. But, instead of forwarding the call, SIPTRunk.com will route it to a voicemail system that plays a generic unavailable message. SIPTrunk.com will record the voicemail and then email it to the email address you specified.
- Login to your SIPTrunk.com portal.
- Navigate to the DIDs tab.
- Scroll down to the desired DID.
- Click on the pencil button next to the DID to edit it.
- In the Vmail-Email field, input the desired email address.
- Click the Submit button.
Custom Voicemail Recording
At this time, SIPTrunk.com does not have the ability for users to upload a custom message for the voicemail to email feature.
