Q:Why I can't upgrade my VP2009 to V30 firmware?

A:V30 can be only used for the models with 256M memory but not for128M because there are some advanced features which have high requirement for the hardware.

How to distinguish 128M and 256M :

1. Make sure the model name on the back label is VP2009P or VP2009T, not VP2009, all models named VP2009 is 128M memory.

2. Check 7th and 6th digits of the SN number count backwards on VP2009.

If these two digits are 01/ 03/ 11/ 13, it’s 256M. If these two digits are 00/ 02/ 10/ 12, it’s 128M.

For some models, this method may be unavailable, so you can check the following point.

3. Check the last digit of hardware version, VP2009 is 256M Memory if it is more than or equal to 8, else it is 128M.

If you do upgrade on VP2009 with 128M memory, it will not succeed and the upgrade process will jump to 100% in a matter of seconds.

Q: Why do Yealink phones use DOB format logo file instead of popular BMP, JPG and so on?

A: The picture the phone can recognize has some special requirements. It is not easy for the phone to resolve a popular picture format such as BMP and JPG. To make it easy, we enable only DOB file. There’s a tool for you to convert a BMP file to DOB. You can download the tool and instructions via http://www.yealink.com/fae/How to change the YEALINK logo on LCD.rar

Q: Is there a SIP message that can make the phone reboot?

From: sip:sipsak@
CSeq: 10 NOTIFY
Call-ID: 1234@
Event: check-sync;reboot=true

Q: What is the difference between user name, register name and display name?

A: Both user name and register name are defined by the server. A user name is used to identify the account while a register name matched with a password is used for authentication if the server requires. Display name is the caller ID that will be displayed on the called party. Some servers also define the display name so this parameter set on the phone may not take effect.

Q: What is PnP which mentioned in auto provision?

A:PnP stands for Plug and Play. It is a method for our phones to get the provisioning URL. If the phone is with PnP enabled, when it boots up, it will send multi-broadcast message to its network, any server (usually the PBX) recognizes the message will respond with the preconfigured provisioning URL, so the phone will be able to download the CFG files from that URL. It needs the server’s support.

Q: What is the principle of a provision?

A: The phone downloads a certain text-based file (CFG format) which contains the configurations or firmware update request. It will know what to do according to the text-based file.
For the detailed explanations to auto provision, you should refer to a specific manual: http://www.yealink.com/fae/Auto Provision Manual.rar

Q: What is auto provision?

A: It means auto configuration, Yealink phones support most of the configuration parameters for auto provision, local phonebook, firmware and so on. You can make auto provision on a single phone, while it makes more sense in the massive configuration.

Q: What is “Semi-attended Transfer”?

A: As defined in RFC5589, it is “a hybrid between a fully attended transfer and an unattended transfer”. We know that when a transferor makes an attended transfer to a certain target, it waits till the target party answers and then complete the transfer, this is attended transfer. If the server supports, the transferor can hang up the call before the target party answers, and the transfer can also be completed, this is called semi-attended transfer. For Yealink phones, there’s an option for you to enable/disable semi-attended transfer.

Q: Why can’t I upload the phonebook via auto provision?

A: Please note that the phonebook you can upload via auto provision must be a local phonebook, instead of a remote phonebook. If you don’t know what a local phonebook format is, you can export a local phonebook to view. The name must be “contactData1.xml”.

Q: When it comes to auto provision, what is the difference between a Common CFG file and MAC-Oriented CFG file?

A: During provisioning, a phone will try to download 2 CFG files, one is Common CFG file and the other MAC-Oriented CFG file. Both files will let the phone know what to provision. Common CFG file will be used by a specific model while MAC-Oriented CFG file will be used only by the phone that is using the specific MAC address.
For example, during provision, for a T28 with MAC 0015651130DB, it will try to download y000000000000.cfg that is for all T28 and 0015651130DB.cfg that is only for this phone. The format of the content of these 2 files is completely the same. If there’s any conflict, the MAC-Oriented file has higher priority. For more details, please refer to Auto Provision Manual.

Q: What is the difference between a remote phonebook and local phonebook?

A: A remote phonebook is placed on a server, while a local phonebook is placed on the phone flash. A remote phonebook can be used by everyone that can access the server, while a local phonebook can only be used by a specific phone itself. A remote phonebook is always used as a central phonebook for a company. That is, every stuff in the company can load this phonebook and each time they reach the remote phonebook, the data is passed real-time from the certain server.

Q: What does “on code” and “off code” mean?

A: They are the codes specified on the server which the phone uses to activate or deactivate a certain action by sending it to the server. On Code is to activate a feature, while Off Code deactivate a feature.
Take the On Code for Always forward for example, if you set the On Code to be *78 (this code is supposed to be a feature code to activate Always forward on the server), and the target as 201. When you enable Always forward, the Forward feature on the phone-side is for sure activated, at the same time the code *78201 will be sent to the server, hence the server-side will also know that this phone is set to Always forward its calls to 201. So, the server-side will be able to get the right status of the extension.

Q: What is “BLF List URI” used for?

A: This parameter is for Broadsoft platform. On Broadsoft, you can set up a BLF group containing several extension numbers. A name should be specified to this group that is the so-called BLF List URI. Normally when you use BLF, you should set them up in DSS Keys and the phone will subscribe to the server for each extension once, with BLF List URI, the subscription will be simplified. The phone will only use the group name of the BLF List URI to subscribe to the server once and the server will know to let subscribe all the extension numbers in that group. This will greatly reduce the heavy burdens on the server.
For example, if you have 10 extensions, normally you will have to subscribe with the server for 10 times from the first extension number to the last. However, if you specify a BLF List URI including these 10 extensions and name it “Sales”, you will only need to subscribe “Sales” with the server, which happens only for once.

Q: If I configure the “Ringer Device for Headset” setting on the WEB UI, why the ring still plays by speaker?

A: If you would like to play ringtone by headset, besides configure the setting of “Ringer Device for Headset”, the Headset should be enabled by pressing the Headset button on the keyboard (the LED of the headset will be on).

Q: How many extension modules can be connected to T28\T26?

A: You can connect at most six extension modules to T28\T26.
Please note that, if you connect more than 3 extension modules to the phone, you need to connect one more adapter for each extension module.

Q: What’s the different between T22&T20?

	LCD	Logo Display	Line	Xml phonebook	SMS
T22	132*64	Picture logo	3 lines	Support	Support
T20	2 *15 characters	Text logo	2 lines	Not support	Not support

Q: What are the main differences between T26&T22?

T26	Support extension module	Support 10 DSS Key
T22	Doesn’t support Ext-module	Doesn’t have DSS key

Q: What’re the main differences between T28&T26?

	LCD	Logo Display	Line Key
