Verify Open SIP firmware
Press Main → Network Information → Software. The "App File" name should start with SIP_ (Open SIP) — for example SIP_J189_4.1.x.x_release.tar. If it starts with S_, you have Aura firmware and need to convert to Open SIP first via Avaya's downloads area.
Provisioning file (recommended)
J100 phones strongly prefer central provisioning over per-phone manual setup. Drop a 46xxsettings.txt on your provisioning HTTP/HTTPS server with at minimum:
SET ENABLE_OPS_SCREEN 1
SET ENABLE_OPS_PASSWORD 0
SET SIPDOMAIN <sip-host-from-portal>
SET SIP_CONTROLLER_LIST <sip-host-from-portal>:5060;transport=udp
SET REGISTERWAIT 360
SET DSCPSIG 24
SET DSCPAUD 46
SET ENABLE_PRESENCE 0
SET ENABLE_AVAYA_ENVIRONMENT 0
Set Provisioning Server on the phone (Main → Administration → Provisioning) to your HTTP server URL. The phone fetches 46xxsettings.txt at boot and applies the settings.
Per-phone manual configuration
- Press Main → Administration (the admin code defaults to
27238= "CRAFT" on a phone keypad; change immediately). - Open SIP → SIP Global Settings.
- Set:
- SIP Domain: the SIP server host shown in your customer portal
- SIP Proxy Server List: the SIP server host shown in your customer portal, port 5060, transport UDP
- Avaya Environment: No
- Reg Wait: 60
- Open SIP → User → Identity for line 1:
- Username: SIP username from VoiceTel onboarding
- Auth Username: same as Username
- Auth Password: SIP password
- Display Name: caller's name
- Save and reboot.
Codec preference
In 46xxsettings.txt, set:
SET AUDIO_CODEC G711U,G711A
SET DTMF_PAYLOAD_TYPE 101
Per phone: Main → Administration → Audio → Codecs; arrange G.711 µ-law / A-law at the top.
