One of OnSIP's many benefits is the ability to bring your own device (BYOD). Our customers can purchase phones that best fit with their companies' needs, and, due to this feature, over 500 supported phone models are in use with our service right now.
With this mingling of devices, issues are bound to pop up.
An issue that frequently arises in our testing lab is performing an attended transfer on a Grandstream phone. (It turns out that this is a popular topic on YouTube!) Eric Phipps, one of OnSIP's NOC Technicians, recorded a video that demonstrates how to accomplish this task.
Transferring a Call on the Grandstream GXP1610
Grandstream developed a different philosophy in regards to performing an attended transfer on their devices. As Eric elaborates on in this video, an attended call transfer is a 3 step process:
- Place the original call (the call you want to transfer) on hold
- Establish a separate call to the transfer destination using the second line on the phone
- Transfer the original call from Line 1 to Line 2
While attended transferring may be tricky at first, it becomes a seamless task once you know what steps to perform.
And remember, this call transfer process is applicable to the entire Grandstream phone line, not just the GXP1610 shown in the video.
You Can Use Grandstream Phones with OnSIP
We built the OnSIP platform on open source technologies and by strictly adhering to the current RFC standards for SIP. Any IP phone that was also built in conformance with these standards will seamlessly work with our service. Read more about the OnSIP Platform here.
