How is OnRelay different from a Virtual PBX or a Hosted IP PBX?

OnRelay delivers a Mobile PBX using standard cellular connections. Virtual PBXs as and Hosted IP PBX to the contrary rely on broadband connectivity and Voice over Internet protocols to deliver their functionality to PCs and Smartphones. OnRelay’s Office Phone System is designed from the outset for the smartphone user to allow businesses to replace a large percentage of their IP deskphone infrastructure with smartphones and cellular connectivity — without losing access to a complete business phone system and office lines. 

Is it possible to use desk phones and PC softphones with OnRelay?

OnRelay supports SIP softphones and desk phones, as well as more advanced SIP extensions such as operator consoles and conference phones. 

Can I use my existing mobile / cellular number and cellular contract?

Yes. OnRelay supports any cellular network globally, whether 3G / 4G, GSM/GPRS or CDMA / EVDO.

How does OnRelay affect my mobile bill?

It will stay about the same, or be slightly reduced.  Mobile calls in business mode are always placed to a local number from the smartphone, so you just need to ensure with your cellular provider that your monthly package of local minutes is sufficient to handle your monthly business call volume.  Since long distance and international mobile business calls are routed via the SIP trunking network, there will be less costs for these calls. 

Do end-users need a mobile data contract?

Yes. A mobile IP network is used for signalling between the OnRelay Office Phone app and the OnRelay server. OnRelay uses advanced mechanisms to manage short term IP connections, preventing battery drain and minimising data usage. Customers should expect to use less than 1MB per user / month of data.

Can I keep my existing business numbers / DID range?

Yes. These numbers can be ported to OnRelay’s SIP trunk provider partners and be connected to individual users as desired.

Is OnRelay just voice over IP over the Cellular Data Channel?

No. OnRelay uses the standard cellular voice path for its media path and is not an ‘over the top’ service or VoIP app. It thereby provides cellular network level quality of service and voice quality.

Does OnRelay use voice over IP over WiFi?

If pairing with SIP extensions are enabled on your account, you may connect a variety of 3rd party SIP softphones to your extension via WiFi. Please however note voice over WiFi solutions have struggled to penetrate the business market in scale due to significant problems with scalability, complexity, network interference, capacity and voice quality in office environments. Due to the associated support overhead, OnRelay therefore does not offer this option as part of its own mobile app, which relies on regular cellular connections.

What if I still want to use my home or hotel wireless network with OnRelay?

If you have enabled the landline pairing option with OnRelay you can do this using a standard SIP softphone from your PC or Mac.  We recommend X-Lite and Bria from CounterPath.

What happens if no mobile data network is available?

You will still be able to receive your calls since normal cellular connections are used.

Does OnRelay work while roaming internationally?

Yes. As OnRelay requires no mobile network integration, it can work seamlessly over any mobile network anywhere in the world. End users experience the same functionality roaming internationally.

How does OnRelay affect cellular call setup times?

As a rule of thumb, OnRelay adds 2 to 4 seconds to the mobile call set-up time. On efficient cellular networks OnRelay offers a consistent 8 to 10 second total setup time. OnRelay has proven to have the fastest and most reliable call setups over 3G/GSM of any fixed mobile convergence solution in the industry.

What is included in the monthly subscription bill?

The fixed line telephony component of all domestic calls, as well as all customer services charges, cloud hosting charges, support, software upgrades and software license fees, are included in the fixed monthly cost. Business calls will however still use of your mobile minutes since a cellular voice connection is used.
