Grandstream GXP2135 IP Phone Firmware 1.0.8.26 Beta Description

IMPORTANT UPGRADING NOTE:

- For GXP2130/2140/2160, once upgraded to 1.0.7.15 or above, downgrading to 1.0.5.x firmware version or lower is not supported.
- For GXP2135/2170, once upgraded to 1.0.7.15 or above, downgrading to 1.0.6.9 firmware version or lower is not supported.
- This release has Predictive Dialing feature which includes a required internal change. If you downgrade from 1.0.8.26 to 1.0.7.25 you will lose the call history
- This release restored the Weather service. Part of the change requires users who are using “Self-Defined City Code” to change their setting. The upstream content provider has changed the API to yield a free-style search based on this argument instead of mapping to a specific code being used before. Hence the city being displayed would have been incorrect. These users should change this option to the name of the city, for instance: “Dallas”; “Dallas, NC”; “Dallas, Scotland”; “Liverpool”; “Liverpool, NY”; “Liverpool, England”.
- Note: If you enter only the name of the city it’s going to go the best match. In the case of Dallas it would be Dallas, TX; and in the case of the Liverpool it would be Liverpool, England.

About VoIP Phone Updates:

Firmware updates for VoIP Phones are very important as they usually contain many bug fixes, add new features and updates, as well as add additional security features.

One of the main problems users come across when attempting to upgrade their VoIP Phone is that their device may be locked to a certain Carrier. Adding an unlocked version of the firmware may cause the device to stop working on certain networks. This operation may void your carrier warranty and, as such, is not recommended.

Before downloading, make sure that you have selected the appropriate firmware for your device and that the update supports the VoIP service provider you use.

Generally, it is important to upgrade older firmware in sequence (v1 to v2 to v3) and so on, because many manufacturers don’t launch standalone update packages.

Although using beta release firmware packages is tempting, it can prove to be quite risky as well. If you choose to try beta release updates, please read the detailed firmware notes and make sure that you have the possibility to revert to an older and more stable version in case the beta turns out faulty.

If you feel that this update can improve the functionality of your VoIP Phone, please use the download button and follow the installation instructions.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
