SIP with Cradlepoint MBR95 and AT&T Mobile Broadband

Walking around with a Polycom desk phone in your pocket? We've got the perfect solution for you! We started testing the mobile network and devices for our sales people looking to demonstrate hosted PBX with desk phones on the road (for conferences and expos). SIP phones are very dependent on a stable network, but many networks block everything except world wide web and email traffic. We wanted to build a network that would allow our team to move from location to location without being dependent on potentially subpar network service. In this article, we deployed a wired SIP phone that runs off of a cellular network to create this kind of network.

Click to Call, SIP Addresses, and the History of Telephone Numbers

The way we use phone numbers has changed significantly since the early 20th century. Cellphone contact lists have made memorizing phone numbers a thing of the past. Restaurants and other businesses have apps that allow users to click to call phone numbers without requiring the users to manually dial the number. Similarly, OnSIP’s click to call feature allows users to seamlessly call any phone number from any web page simply by clicking on it. The click to call add-ons are Firefox and Chrome extensions that look for phone numbers in the web browser and automatically turn them into links. When such a link is clicked, a call is made to OnSIP’s web-service-based call-setup API. The API then places a call to the person’s desk phone, based on the SIP address configured in the Chrome or Firefox plugin, and when the person picks up, an outgoing call is placed to the number in the link.

The way humans have used phone numbers represents how telephony has evolved over the past 100 years. When phones were a rarity, it was not uncommon for telephone numbers to be a single digit long. As early phone usage increased, telephone numbers became two to three digits. The numbers were given orally to switchboard operators who would manually connect two parties via a physical wire. In rural areas, users of magneto telephones literally had to crank the phone to reach the intended party.

OnSIP Interview with Planet Cassandra

Apache Cassandra is a massively scalable open source NoSQL database. Cassandra was designed to manage huge amounts of structured, semi-structured, and unstructured data across the cloud. Facebook initially developed the solution for their Inbox Search feature, and OnSIP has utilized it to horizontally distribute our platform. Google, Cisco, Reddit, and Netflix are just a few companies who are also utilizing Cassandra.

VoIP capabilities on T-Mobile Broadband Network

T-Mobile US services 34 million customers and has annual revenues of $21.35 billion. With such a sizable presence, the quality of T-Mobile's broadband network has serious ramifications for a significant number of VoIP users. We put T-Mobile’s broadband network to the test to see if its VoIP capabilities were up to par.

We picked up a Huawei webConnect Jet modem and a pre-paid SIM card kit from T-mobile. We paid the minimal amount of data available for our testing purposes - $15 for 300 MB. Then we plugged the modem directly into a Macbook Pro, and we were instantly able to register our SIP devices without any issues.

We review the Grandstream GXP2200 Enterprise Multimedia Phone for Android


For the past few weeks, we've been using Grandstream's newest touchscreen, Android-based IP phone, the GXP2200, and absolutely loving it. This 6-line phone comes packed to the brim with features: HD wideband audio, 5-way conferencing, PoE, bluetooth support, electronic hook switch with Plantronics headsets, video calling and more. The touchscreen this time around is very responsive, making navigating through menus and using onscreen applications completely pain-free.

Are Facebook VoIP calls on Android Using WebRTC?

Facebook is no stranger to VoIP technologies. The company began offering free VoIP calls on iOS devices a few months ago, and the Android service was available in 23 other countries before making its official debut in the States. Facebook, like Google, wants to become the catchall for online communication and social networking, and this introduction of VoIP services is a step toward heightened integration.

Announcing New Feature: OnSIP Lights Up Busy Lamp Field

For a long time now, office receptionists and call center managers have relied on phone sidecars and flashing buttons to get a bird’s eye view of which co-workers were on a call. The phone’s flashing lights, Busy Lamp Field, seems a simple enough feature. However, it’s not so simple in a world today as businesses increasingly need geographic flexibility, the ability to connect multiple offices, remote workers, and traveling employees with smart phones.

Today, businesses require phone systems that are just as complex as they are. But the fundamental need of being able to see when a co-worker is on a call has never changed. That’s why OnSIP has innovated its own Busy Lamp Field (BLF) support. It’s a technology that gives you an accurate snapshot of your phone system, regardless of where your co-workers are located or what phones they’re using.
