Escene ES / WS series — setup for our PBX

Escene (the Chinese company 广州市亿景通信 of Guangzhou) makes inexpensive desk IP phones in the ES and WS ranges, which were installed by the crate in CIS offices and venues throughout the 2010s. The models are discontinued but alive: they are all configured the same way and they do work with our PBX.

The factory web login for the whole range is root / root, and the default address, when there is no DHCP on the network, is 192.168.0.200.

A note on language. The old escene.cn domain does not respond; the vendor's live site is escene.com.cn, and the manuals there are in Chinese. The field names below are given in translation with the manual's original in brackets so you can match them against your screen. On English firmware the same fields read Enable, Display Name, Account, Authentication Username, Password, SIP Server — ⚠️ verify: that mapping is by meaning; we have no English-language vendor manual.

Common credentials, ports and network requirements are on the overview page “SIP phone setup”.

What you need#

• Extension credentials from the admin panel: Admin panel → Telephony → Operators tab → “Reset password” on the operator (how to get them).
• The phone connected by cable through its LAN port to the same network as your computer. Power comes from PoE on builds with a P in the name (ES270-P, ES280-P, ES330-PEG) and from an adapter on the rest.
• A computer with a browser on the same network.

Step 1. Find the phone's IP address#

On the phone: Menu → System settings (系统设置) → View status (查看状态) → Network status (网络状态) — the display shows the current IP address, MAC address, mask and gateway.

If there is no DHCP server on the network, the phone comes up on its factory address 192.168.0.200. To reach it, your computer temporarily needs an address in the same subnet, say 192.168.0.50.

The address type (DHCP, static or PPPoE) is switched in the same place: System settings → Advanced settings (高级设置) → Network (网络) → LAN port settings. The advanced-settings password is empty from the factory — just confirm.

Step 2. Log in to the web interface#

Type the phone's address into your browser: http://<phone IP> (or http://192.168.0.200 if the address is still the factory one).

After logging in you land on the Phone status (话机状态) page: firmware version, registration state per account and network parameters. The sections are listed on the left.

The administrator password is changed in the phone's maintenance section. If the factory root is refused, the password has been changed; it cannot be recovered, only reset together with the phone.

Step 3. Enter the PBX credentials#

Open the “Account and server settings” (账号及服务器配置) section, pick an account (账号 1) and the “Basic” (基础) block:

Leave Backup server (备用服务器), Outbound proxy (外出代理服务器), STUN server and NAT Traversal empty and switched off. Save the settings.

Step 4. Verify the registration#

• In the web interface: the Phone status (话机状态) home page shows the registration state of each account — registered or not.
• On the phone: System settings → View status → Line status (线路状态); in idle state a registered account shows its name on the home screen.
• In the admin panel: Telephony → Operators — a green dot lights up next to the operator, together with the string the phone used to identify itself. The status comes from the PBX and refreshes at most once a minute.
• A test call: dial a colleague's extension.

Factory reset#

A reset is needed if the phone was bought second-hand (it still holds someone else's account and, worse, someone else's provisioning address, which will overwrite your settings on every reboot), if the root password has been forgotten, or if the phone behaves unpredictably. Everything is erased: SIP accounts, network settings, the web password, the phone book, the language.

Method 1. From the phone. Menu → System settings (系统设置) → Advanced settings (高级设置) → the advanced-settings password (empty from the factory) → Restore factory values (恢复出厂值) → confirm.

Method 2. From the web interface. The phone maintenance section → Restore factory configuration (恢复出厂配置). The manual warns explicitly: after a reset from the web interface the phone has to be rebooted, otherwise the settings do not take effect. The result is the same as resetting from the phone's own screen.

The neighbouring item, Change password (密码修改), is where the web account is changed — the factory username and password are both root.

After the reset. The phone takes an address over DHCP again, or comes up on 192.168.0.200 if there is no DHCP server. The web login is root / root once more, the advanced-settings password is empty again, and the SIP account has to be entered from scratch.

If the phone does not register#

1. The extension number was typed into the login field. Account (帐号) and Authentication username (认证用户名) must hold the whole sip-xxxxxxxx-<extension> string, not “101”.
2. The “Enable” box (是否启用) is unticked. The account is filled in but switched off, and the phone does not attempt to register.
3. The account's SIP server field is empty. The phone then falls back to the global SIP settings — which may hold nothing, or someone else's address. Fill the field in the account itself.
4. The password came from the wrong window. An extension password is shown once; if it was not saved, click “Reset password” in the admin panel and enter the new one.
5. The phone is on the wrong subnet. Without DHCP it sits on 192.168.0.200 and on a 192.168.1.x network sees neither the PBX nor your browser. Switch it to DHCP (step 1).
6. TLS is selected as the connection type. Our PBX does not offer TLS/SRTP encryption: Connection type (连接类型) must be UDP.
7. STUN or NAT Traversal is on. We need neither and both get in the way: switch them off.
8. SIP ALG on the router. Registration works but the call drops or only one side is audible — switch SIP ALG off (details in the overview).

Frequently asked questions#

escene.cn does not open — is the vendor still around?#

It is. The old escene.cn domain does not respond (checked on 2026-09-09), but the company operates under escene.com.cn, where the manuals and firmware are published by model — including the discontinued ES220, ES290, ES320, ES330, ES410 and ES620: the Downloads section, discontinued-products subsection (退市产品).

The manual is in Chinese — how do I know what to press?#

The field names on this page are given in translation with the Chinese original in brackets: match the characters against your screen. The phone and the web interface can both switch language (English is in the list), so it is easier to switch the interface to English once and use this page for the meaning of the fields.

Can several extensions be registered on one phone?#

Yes. The junior models take two independent SIP accounts and the senior ones (ES620) up to eight, each able to point at its own server. Fill in the second account exactly like the first, with a different login and password.

Does auto-provisioning work with your PBX?#

No, the platform has no provisioning server — the phone is configured by hand as described above. If the phone was bought second-hand and still holds the previous operator's server address, your settings will be overwritten on every reboot: start with a factory reset.

The phone is from 2015–2020 — is it worth connecting at all?#

It is, if it works: all we need is plain SIP over UDP on port 5060 with the G.711/G.722 codecs, and Escene has had that from the start. The one thing to keep in mind is that the model is discontinued, so there will be no new firmware or vendor support — for a new venue's main phone something from a current range is a better bet.
