Phones & feature codes
Every user can see their own phone settings in My Phone → Settings → Phone setup. Here's what goes where.
Phone settings
| Setting | In the office | Away from the office |
|---|---|---|
| Server / domain | PBX IP, e.g. 192.168.1.10 | sip.example.com |
| Port | 5060 | 5061 |
| Transport | UDP | TLS |
| Outbound proxy | (none) | sip.example.com:5061 |
| Media encryption | off | SRTP (SDES) |
| Username / auth name | extension number, e.g. 8800 | same |
| Password | the extension's SIP password | same |
| Re-register | default | every 60–120 seconds |
Zoiper on a mobile phone (away)
Account → domain sip.example.com, transport TLS, outbound proxy sip.example.com:5061. Under Advanced → Encryption choose SRTP (SDES), not ZRTP. Android and iOS can close a background app's connection — allow Zoiper to run in the background (or use push), or incoming calls go to voicemail.
Desk phones
Set Proxy, Registrar and Outbound proxy to the PBX IP, port 5060, transport UDP, and turn SRTP off on the LAN. If you use "dial 9 for an outside line", update the phone's dial plan (e.g. 9xxxxxxxxxx).
The phone appears under Dashboard → Signed in now as Online, showing whether it's internal or external.
Feature codes
| Dial | What it does |
|---|---|
911 (also 9911 / prefix + 911) | Emergency call. Always connects. |
933 | Provider test line: reads back your E911 address |
*97 | Check your voicemail |
*98 | Record your voicemail greeting |
*60 | Join the conference room |
*555<ext> | Monitor an extension's calls — stays on the line, auto-follows new calls (admins only by default) |
*555 | Scan mode: listen to any active call on the system |
*70 | DISA: outside dial tone after a PIN (only if a PIN is configured) |
*86 (during a call) | Block the caller mid-call: the call ends, they hear "the number you have dialed is not in service", and their number lands on your block list. Only keys from your own phone count. |
| ring group or IVR number | Ring that group or menu |
While monitoring (*555), press * / 1 for the previous call and # / 2 for the next call. A beep confirms each hop. Hang up to stop.
Controlling access
The Features page in the admin panel controls every star code: turn each one on/off for the whole system, set the default access (All users, Admins only, or No one), and override per user with Allow/Deny. For example, give *555 (ChanSpy) to a supervisor without making them a full admin, or disable *70 (DISA) entirely.
