The following review was conducted in March 2017.
The Yealink SIP-T19P E2 is a redesign of an earlier model, the Yealink SIP-T19P, which is on its way to being discontinued. The newer model preserves the popular features of the legacy phone, while expanding its capabilities and adding tweaks.
The Yealink SIP-T19P E2 is an entry-level device with better functionality than other similar low cost options. The phone offers a single SIP line, with full call control functionality and HD codecs, making it ideal for low call volumes. This device would work well in a home office, a public waiting room, or any non-intensive calling environment.
The Yealink SIP-T19P E2 is a solidly designed device with button placements that make sense. The economical layout offers instant access to many of the most used features for business phones. The phone’s screen is small but sharp, and presents information clearly with little lag.
There are specific buttons for popular phone features, like redial, transfer, mailbox shortcut, speaker, mute, and headset. Four buttons are programmable, which allows users to customize their functions. The default functions include do not disturb (DND), phone directory, and call history. If you find that you need other functionality for the soft keys, such as intercom and paging, you can do so using the web interface.
The only minor oddity we noticed was that the there is no built-in microphone on the body of the phone. If you use the speakerphone, the phone appears to use the handset as the audio input.
The Yealink SIP-T19P E2 features the full SIP stack of the Yealink phone line. While the phone only accommodates one SIP line, it offers 3-way conferencing and attended transfers, which are not found on most other entry-level phones on the market.
Other calling features include:
- Call hold, mute, DND
- One-touch speed dial, hotline
- Call forwarding, call waiting, call transfers
- Group listening
- Redial, call return, auto answer
- Local 3-way conferencing
- Direct IP call without SIP proxy
- Ring tone selection/import/delete
- Set date time manually or automatically
- Dial plan
- XML Browser, action URL/URI
- Integrated screenshots
- 132x64-pixel graphical LCD screen
- Anonymous calling, anonymous call rejection
As an upgrade, the phone now provides HD voice codecs, which wasn't always the case for Yealink's entry-level devices. The SIP-T19P E2 also features the full web UI functionality of other Yealink devices, which makes it very customizable. If your phone system has an uncommon feature or need, this phone may support it.
Unfortunately, Yealink is one of the last manufacturers on our provisioning server that still doesn't support music on hold as suggested in SIP RFC 5359. We're hoping they will soon.
The Yealink SIP-T19P E2's sound quality is decent, but if you need high voice quality in your conversations, you may be frustrated by the phone’s slightly muffled sound.
In conversations with other SIP devices that also use the G.722 HD codec, the SIP-T19P E2 experienced a noticeable dip in sound quality. This did not make the phone unusable, just noticeably less clear. We found the sound quality to be not as good as more advanced phones from Yealink, but still acceptable for everyday use.
OnSIP Interoperability Testing
At OnSIP, we put each of the phones we use through a multi-step interoperability test in which we apply ~30 test cases. An example of a test case would be the following:
Test phone calls phone B
B picks up
B puts Test phone on hold
B calls phone C
C picks up
B transfers test phone to C
Call must be transferred correctly to C. B must be released correctly after the transfer. When C picks up, audio must work in both ways between test phone and C. When test phone is on hold, there is no audio between it and phone B.
Aside from the aforementioned Music on Hold feature not using the same RFC standard as OnSIP, the Yealink SIP-T19P E2 works exceptionally well with OnSIP. Transfers, hold, and conferences all work with our other test devices (Bria for OSX 4, Polycom VVX 410). The phone was able to navigate through all of our offered products such as queues, IVRs and voicemail.
OnSIP Phone Registration
Step 1: Gather information for each user
For each phone that you are configuring, obtain the following credentials. You can find this information in the user detail pages under the Users tab in the Phone Configuration section of the OnSIP Admin Portal.
Step 2: Log into your Yealink phone through a web browser
When your phone is powered on and connected to your LAN, use a browser on the LAN to navigate to the IP address of the Yealink SIP-T19P E2.
Step 3: Enter Account Information
Select the 'Account' tab, and navigate to 'Register'. Enter your account information.
- Account Active > Select "On"
- Label > The soft key label for this line
- Display Name > What you would like others to see when you call them
- Register Name > "Auth Username"
- User Name > "Username"
- Password > "SIP Password"
- SIP Server > "Domain"
- Enable Outbound Proxy Server > Select "Enable"
- Outbound Proxy Server > sip.onsip.com
Step 4. Confirm that your phone is registered.
In the Admin Portal, click on the "Users" tab. You will see a green "online" notation next to each user with a registered phone.
The Yealink SIP-T19P E2 is an excellent re-release of Yealink’s entry-level phone. The market price of $50 makes it an economical device, and Yealink’s reliable SIP software and phone functionality makes it easy to use. The screen is better than comparable phones from Polycom and Grandstream, though the sound quality takes a noticeable dip. If you’re looking for an easy deployment of single line phones, this a a solid option.
