Status → Calls & Registrations shows the live state of the telephone system. The page refreshes itself every 5 seconds, so you can leave it open while you test a phone or a provider.

Asterisk

The first line shows the Asterisk version, the number of Active channels (every call leg counts as one channel, so a call between two phones usually has two) and SIP phones registered: how many of the SIP phones currently have a registered device, out of all SIP phones.

If the page shows Asterisk is not reachable with an error, the telephony engine is not running or does not answer. Look at the Asterisk log under Status → Logs; applying the configuration again or a reboot usually brings it back.

Providers

ColumnMeaning
NameName of the provider.
TypeSIP or IAX.
Registration / stateFor SIP providers that register: the registration state. For SIP providers without registration and for IAX providers: whether the provider is reachable. Disabled providers show disabled.

not loaded means the provider exists in the configuration but is not active in Asterisk yet; apply the pending changes.

Phones

NameCaller ID name of the phone.
StateDevice state reported by Asterisk, or disabled.
ContactFor each registered device: its address (SIP URI), the qualify state and the round-trip time in milliseconds. Empty when no device is registered.
User agentMake and firmware the device reports, for example the softphone name and version.

External phones (numbers that are dialled through a provider or a SIP URI) are not listed, as they never register.

States

The coloured dot next to a state shows its meaning at a glance:

  • Green: Registered, Reachable, Not in use, In use – the phone or provider works.
  • Grey: unknown – Asterisk has no information yet, for example right after a start.
  • Red: every other state, such as Unregistered, Rejected, Unreachable, Unavailable or not loaded.

A red state for a phone usually means that the device is switched off, not configured, or cannot reach the PBX. For help see Troubleshooting.
