The Phone Device is the actual "phone" you use for the Offisky phone system. A phone device can be anything from a IP Phone, a ATA Digital to Analogy phone converter, a software phone (soft phone) that can install in your computer, or a phone app that installed in your smart phone. As long as your Phone Device is running under SIP protocol, it can be use within the Offisky phone system. In order to enable Offisky to communicate with your phone device, it needs to setup to connect to its corresponding "Phone Device Account" within your Offisky phone system. After your phone device has successfully connected to the network, you can create different mapping rules within your Offisky phone system to connect to the Phone Device Account.

This screen provides the detail information how to setup your local device to connect to this Offisky phone system device account. Even though each device brand may have its own user interface to configure their device, but they follow the similar concepts, this document will cover the most common settings you need to perform to setup your local device.

Panel Location:
User Menu >Under Settings, select (Phone System). In the top navigation menu bar, select PBX Base > Phone Device Account > Select the device account [] > Credential (Tab)


Before continue to review your settings and credential information, please make sure you have understand the following risk.

  • The Offisky phone system device account credentials is one of the most important piece of information you need to connect a local device to your service. If anyone grant access into this information, they can be able to use your account anywhere in the world on your behalf, and you will have to take responsibility to the action of what he/she has performed. Offisky has perform the maximum effort to safe-guard your account, however, it is your responsibility to protect yourself against any possibilities which may abuse of your account.

    • Do not display this credential information in a public computer, or a computer you are not 100% trusted. Computers without proper protections may contain virus or spy programs which may expose your computer information to online hackers. Continue with this screen using improper computers may result in account hijacking.

    • Do not provide credentials or setting information to anyone you are not 100% trust. You should only provide these information to anyone you 100% trusted. Whoever hold these information may gain access and use your Phone System anywhere in the world, and you are taking full responsibility to all actions made on your account.

    • Destroy all copies (in any form) of this setting information once the setup is finished. To avoid any unexpected situation. Make sure you have destroy all the copies of this information (in any form, ie. hard copy, soft copy, etc) after your setup is finished. You can always get this information through this panel in the future.

    • Avoid using your device under insecure network, or using unknown software phone or SIP phone apps. Using insecure device software or run under insecure network may also create potential risk to expose your credential information to attackers.

    • If something suspicious happen, reset your credentials. You may, at any time, reset any / all your device(s) credentials through this panel to protect yourself from any potential risk. Just keep in mind if you wish to reset your credentials, make sure you have disable the connectivity between your device to the Offisky phone system first, then perform your device update. Otherwise, the system may receive too many invalid attempt and may block your IP Address to protect your account.


  • Once phone device account can only use by one phone (one line or extension within your phone) at the same time. If multiple phones connected to the same Phone Device Account, they will be conflict to each others, which will result in call delivery errors.

  • If the phone device account experience excessive failure access (ie. invalid authentications), the connecting IP address will be block by the system to protect your account. In such case, if you are in the middle of setup your local IP phone settings, it may result in the complete phone network interruption within the same public IP. To avoid this, always copy and paste the information from this screen to your phone settings, and make sure all the settings are valid before allow your phone to go online and connect to the service. If this is really happening, create a ticket in the support channel to request for IP unblock, and provide us with the complete reason of why is this happen.

To setup your local device:

As we describe earlier in this document, each device brand may have their own user interface to configure their device, but they all follow the same concept. The following procedure has guide you to perform the most minimal settings to connect to your Offisky phone system. Please note: Offisky only support devices which is run under SIP Protocol.

  1. Access into your device configuration system (ie. Web Configuration Panel, or configuration script). If username / password is required, use this device administration username and password (not the account device credentials). For more information, please refer to your local device setup Menu.

  2. Setup Account / Line Settings:

    • Search for lines / accounts settings, and select the line / account you wish to use to connect to Offisky phone system. If the current device is only use for this device account, use the most "Global" line settings.

    • Screen / Display Name: The name you wish to display on the device, recommended using the Device Name for easy management.

    • Username / Register / Labels / Numbers / Phone Number / Caller ID / Auth. Name / etc.: Different brand may use different name on this, or even multiple entry, always provide the username within your Offisky device account (copy and paste recommend to avoid error)

  3. Disable all build-in call features:

    • Some devices (ie. Cisco, Grandstream) comes with build-in call feature on the phone, which will conflict with the Offisky phone system feature and must be disabled.

    • You must allow 3 digits * code (EG. *011) to use the full list of options (unless you only plan to use Offisky panel to make calls).

  4. Disable call re-direction:

    • Offisky phone system does not use the standard SIP header triggered call redirection (ie. call transfer), instead, it will use DTMF to trigger the transfer request. Please refer to phone system feature list for details.
