Voicemail Trunk

Overview

Default Voicemail with audio transcription 📫📝 is linked to a Connection. This means it is reached when SIP To header has a value of that Connection's SIP User

Although you can send other Connections to the same voicemail by simply configuring a Call Flow on them, you may prefer to have a dedicated SIP URI that accepts any SIP To value (SIP user), even those without a corresponding Connection

With elastic SIP Trunking you can create a shared voicemail

Use Case

Send call with any SIP To header to single, shared voicemail

Setup

1. Create a Call Flow with Voicemail deposit action (see Voicemail box)

2. Create a Trunk. Select a name and SIP URI (see Trunk) for SIP input type (you can enable PSTN input too and you can also keep it PSTN-only but that can't multiplex SIP users)

1. Attach your Call Flow from Step 1 (see Trunk)

You will likely leave Trunk OUT section of your Trunk disabled. In some more specialised scenarios you may enable it to send call further: to PSTN, mobile number or to another SIP URI

✅ You now have created a SIP Trunk with a flow that will accept call with any SIP To header and send them all to voicemail
