Voice System
Manage SIP trunks, DID phone numbers, rate cards and voice settings, and monitor calls live and historically.
Voice administration
The Voice System area is where you run your organization's telephony: connect carriers over SIP, assign phone numbers, control per-destination pricing and watch call activity as it happens. Voice settings let you tune defaults like caller ID, recording policy and codecs for the whole workspace.
SIP trunk management
Register carrier trunks, set credentials and capacity, and check registration status at a glance.
DID phone numbers
Manage your inventory of direct inward dialing numbers and route each to a user, team or service.
Call history
A searchable record of every call with direction, duration, parties and outcome.
Active call monitoring
A live board of calls in progress, so you can spot stuck channels or unusual volume immediately.
Adding a SIP trunk
- 1
Create the trunk
Under Voice, add a new SIP trunk with your carrier's host, port and authentication credentials.
- 2
Verify registration
The trunk list shows registration status; a green state means the carrier accepted the connection.
- 3
Assign DID numbers
Attach the numbers provided by the carrier and route each one to its destination.
Place a test call in both directions after adding a trunk. Misconfigured credentials or codecs usually surface as one-way audio or failed inbound calls.
Rate cards
Rate cards define what calls cost per destination, separately for PSTN and SIP routes. Use them to control spend and to bill usage back to teams accurately.
| Route type | What the rate card controls |
|---|---|
| PSTN | Per-minute pricing for calls to the public telephone network, by destination prefix |
| SIP | Pricing for calls carried over SIP trunks, typically lower than PSTN equivalents |
Monitoring and history
Active call monitoring shows every call in progress with its trunk, duration and parties. Call history keeps the full record afterwards, filterable by date, number, user and trunk — useful for troubleshooting quality complaints and reconciling carrier invoices against rate cards.
Call history records call metadata. Whether audio is recorded is controlled separately by your recording policy in voice settings.
