Yealink T27 Series User manual

Beginning in PBX software version 5.2.1-10, we have begun including more integrated support for Yealink
phones. They can now be found via autodiscovery and assigned to extensions, although they do not currently
respond to configure or restart commands. Yealink phones CAN autoprovision from the pbx once assigned,
however, by either logging into each phone's webGUI, or using our quick setup utility. The quick setup utility can
be downloaded here Yealink Quick Setup utility
Auto Provisioning a Yealink Phone
PBX ver 6.0.5 or later method
Starting in version 6.0.5, we have added the ability to configure and restart Yealink phones from the autodiscovery
section of the pbx, eliminating much of the process previously needed to set these phones up.
1) Under Destinations=>Autodiscovery, after scanning the network, go to the commands tab and click the Yealink
Detect link:
2) Press the Start button
3) In the list of phones discovered, you can now check the boxes, and assign, configure, and restart them as if they
were IPitomy HD phones, using the buttons at the top of the page.
Important notes:
This only works for FACTORY DEFAULTED Yealink phones. Phones that have been previously
provisioned will NOT respond to configure or restart commands from this process.
The Yealink discovery function will run for about 10 minutes before shutting itself back off. You can restart
it by going to the commands tab and hitting start, if it has stopped. If it is running, it will say
"http://wiki.ipitomy.comListening"http://wiki.ipitomy.com on that page.
PBX ver 5.2 method
You must assign a phone to an extension either manually or using Auto-Discovery:
Manual ? Navigate to Destinations -> Extensions -> Edit Extension -> Advanced and enter the MAC address of
the phone into the ?Phone MAC:? field. SAVE CHANGES then APPLY CHANGES.

Auto Provisioning a Yealink Phone 1

Auto Discovery - If the phones are on the same LAN as the PBX you can use Auto Discovery. Navigate to
Destinations -> Extensions. Click the ?Auto-Discovery? tab at the top, and then click ?Auto-Discovery (scan
network)?
Once the scan has completed:
1. Select the extension you would like to assign to the Yealink phone(s) from the drop down list.
2. Check the box next to each Yealink phone you are assigning.
3. Click the Assign button.
This will automate the process of entering the Yealink phone?s MAC address into each extensions Phone MAC
field in it?s advanced settings section.
?Yealink phones shown in the Auto Discovery section will not show up colored green even though they may well
be assigned and using the PBX. The coloring is merely cosmetic and will not affect the operation of the phone.
Once the phones are assigned to extensions they can now be provisioned, either manually or if the phones are on
the same LAN as the PBX the Quick Setup utility can be used.
Log into the GUI interface of phone via its IP Address (user: admin/pass:admin)• Navigate to Settings=>Auto Provision• If the phone is local: Set Server URL to
TFTP://<IP address of pbx>/
•
If the phone is remote: Set server URL to
http://<public IP address of pbx>/ippbx/phonecfg/
•
If the phone is remote: Set the username to admin, and the password to 1234• Click Confirm at the bottom of the page• Click Auto Provision Now•
The phone's screen should change to indicate that it is updating its config, and will then register if successful.
NOTE: All Yealink conference phones can use the CP860 phone type for provisioning
NOTE: You can use the Yealink Generic phone type for provisioning a single extension to Yealink DECT
Wireless phones W52P & W56P, additional extensions must be manually added.

To Remove/Disable the DND Softkey on Yealink Phones:
Add this line: features.dnd.allow = 0
to the Yealink Phone Configuration Template found in PBX Setup -> Phone Global. (add the line to the
"http://wiki.ipitomy.comOptions found in the MAC config"http://wiki.ipitomy.com section) Save and Apply
settings then reboot the phones.
NOTE: Yealink T27 models the DND Softkey remains visible on the phone, but it is disabled so pressing it will
not activate DND mode.
Multicast
To set up multicast on your Yealink phone:
Log into the GUI interface of phone via its IP Address (user: admin/pass:admin)• Navigate to Contacts=>MulticastIP• Populate the Listening Address field with the mutlicast IP of the multicast group built in the PBX, followed
by a colon and the port configured for the group.

A dealer has brought to our attention this link to a Yealink forum that has a firmware for multicast. I know in our
testing, the .143 version had the settings needed. But its possible you may need this version as that is what the
dealer needed, so we are linking to the information.

Tones
Yealink phones do play a tone when they receive a unicast page, it is tied into the ringer volume, so if it is set too
low it is very difficult to hear. There is currently no way to use another tone for this, but we can tweak the tone that
does play a little bit so that it can be better heard. Log into the phones web interface, click the
"http://wiki.ipitomy.comSettings"http://wiki.ipitomy.com tab at the top, and then select
"http://wiki.ipitomy.comTones"http://wiki.ipitomy.com from the menu on the left.
The "http://wiki.ipitomy.comAuto Answer"http://wiki.ipitomy.com tone is what plays when the phone receives a
unicast page. We can adjust the frequency of that tone to be a little bit more noticable then the default. We
recommend setting the Auto Answer field to:
2000/500,0/1000
then click "http://wiki.ipitomy.comConfirm"http://wiki.ipitomy.com to save.
Enable and Configure User Access Levels
Here is what you need to do to implement User Access Levels on Yealink phones. Add the following lines (colored
green) to the Common Config section of the Yealink Phone Configuration Template found in PBX Setup -> Phone
Global:
To enable user access levels add this line:
static.security.var_enable = 1
Set default user access level to user:
static.security.default_access_level = 0
URL path for WebItemsLevel.cfg replace IP with what the PBX is set to:
static.web_item_level.url = tftp://192.168.1.249/WebItemsLevel.cfg
Yealink
Multicast 4

Set passwords change newpassword for each login level:
static.security.user_name.admin = admin
static.security.user_password = admin:newpassword
static.security.user_name.var = var
static.security.user_password = var:newpassword
static.security.user_name.user = user
static.security.user_password = user:newpassword
Upload the WebItemsLevel.cfg file to the TFTP Files section found in PBX Setup -> Services this is the file that
sets level access to every option and setting on the Yealink phones. I already set this one to lock out every setting
that could alter the phones operation using the phone menu in any way, however feel free to edit it as needed.
Turning on the user access levels activates a third login "http://wiki.ipitomy.comvar"http://wiki.ipitomy.com we
recommend to just set the password for var to be the same as the admin password.
Also when we set the default user level to "http://wiki.ipitomy.comuser"http://wiki.ipitomy.com, pressing and
holding the OK button for 5 seconds to return the phone to factory defaults will no longer work since that is an
admin level function.
Save and Apply Changes, then reboot the phones to download the new configuration.
Here is the WebItemsLevel.cfg file (you will need to un-zip it first)
FILE LINK: WebItemsLevel.zip
The numbers after each line entry define the user level needed to access that particular setting/feature.
The settings that relate to accessing settings/features by using the Menu in the phone are found under the [GUI]
section.
0 = User
1 = Var
2 = Admin
Remote Phonebook files
Yealink phones use a specific XML format for remote phonebook files.

Enhanced DSS Keys
In Yealink V81 and greater firmware version, the phones support a feature called EDK (Enhanced DSS Keys) that
can be used to program advanced dial strings.
1. Modify the Yealink Global Template under PBX Setup -> Phone Global. Enable EDK feature via auto
provision by entering the parameter as below:
features.enhanced_dss_keys.enable=1
Be sure to save and Apply Changes, then reboot the phone.
Now there will be a "http://wiki.ipitomy.comCustom"http://wiki.ipitomy.com key type added to the phone istelf.
Log into the phone and set a key to "http://wiki.ipitomy.comCustom"http://wiki.ipitomy.com and the set the value
by using the EDK commands:
$C<command>$
Hang up (hu)• hold (h)• waitconnect (wc)•
Yealink
Remote Phonebook files 6

pause <number of seconds> (p <num sec>) where the maximum value is 10•
Example: 4411$Cwc$$Cp10$ defines dialing 4411>>waitconnect>>connected and lasts 10 seconds
$T<type>$
invite• dtmf• refer•
Example: *338$Tdtmf$ defines sending the *338 by the type of dtmf
To program a custom key to dial VM pause a moment and then enter the VM PIN 4321:
923$Cwc$$Cp2$4321$Tdtmf$
Agent Log IN / Log OUT using a custom key:
Log IN example using agent number 444 and password 777:
2*$Cwc$444#$Tdtmf$$Cp2$777#$Tdtmf$
Log OUT example:
3*$Cwc$444#$Tdtmf$
Hot Desking
Yealink phones support hot desking via DSS key. At the moment, this has to be programmed directly on the
yealink phone itself. In a future release we will have a key option on the pbx for autoprovisioning.
Pressing this button on the phone will bring up an on-screen prompt asking for the new extension and SIP
password (found on destinations->extensions, target extension number, and under the advanced section).
Entering the new extension information will keep your current sip server address (usually the pbx or cloud
instance), and all of your current DSS keys, but will use the new extension number. Use the button again to
change back to the previous extension as needed.
Yealink
Enhanced DSS Keys 7

NOTE: Be sure to avoid having 2 phones programmed with the same extension at the same time, as they will
conflict over the registration. It's best to have specially designated
"http://wiki.ipitomy.comfloating"http://wiki.ipitomy.com extensions for phones that are expected to be used with
hot desking.
As a general tip, it may be advised, as an ease of use for the end user, to change the SIP password to something
easier to type on the phones being used, such as an all-numeric password. If you do this, be sure you are also
increasing pbx security to compensate, either via log watch & ban, or sip ACL rules, as making the password
easier will also make it easier to guess for malicious outside attackers.
Fixes
T38G firmware version fixes an issue with Parked calls bonding with other calls incorrectly. Extract the
.rom from the Zip folder and load it into the phone.

Transfer/Park tips
When transferring or parking a call, the "http://wiki.ipitomy.comEnd Call"http://wiki.ipitomy.com softkey does
NOT complete the operation. It cancels it. In this case, it leaves the call on hold instead of moving it where it was
intended to go. Complete the transfer with the "http://wiki.ipitomy.comTransfer"http://wiki.ipitomy.com softkey
instead.

Blind Transfer, Attended Transfer, Semi-Attended Transfer
Transferring a call to an outside number
On a Yealink phone, a DSS key can be created to transfer a call to a specific outside number. You can use the
DTMF Key Type (Transfer key type is going to be available in a future release) and either a system speed dial, or
an arbitrary number, as follows:
Key Type: DTMF Value: ##number# (this does a blind transfer to whatever number you set for it, such as one of
the 2 digit system speed dials, or a full 10 or 11 digit number, as required by your provider) Label: An on screen
label for this key
This is useful if you frequently transfer calls to the same number. System speed dials can be found under PBX
Setup=>Feature Codes, at the bottom of the page.
