Android Open Source Project Robot Picture

Many users want to run a softphone on their Android or iOS smartphone to connect to their business phone system, and it’s pretty easy to do. There are numerous commercial products like Counterpath’s Bria and Zoiper available and open source solutions like csipsimple (for Android) as well. The problem with all of them is that they have to present a different dialer for the user. This is confusing and in the end, the user ends up not using the softphone because it’s a different experience.

What if you didn’t need to fumble with a third-party dialer on your smartphone? Did you know the Android dialing application has the ability to connect to your business SIP phone system? That’s right, there’s an integrated SIP client built right into your Android phone… right under your nose. Unfortunately for iOS users, they’re still stuck with third-party applications.

This capability has been in Android for quite some time and got a lot better around Android 6 (Marshmallow). You can use the client for all outgoing calls while registered or dial only those contacts with a SIP address. Additionally, you set it to not take inbound calls (i.e., don’t register to the system… saves battery). There are still a few issues with the dialer but with the proper configuration, you’ll at a minimum have an easy way to receive calls at the same time as on your desk phone vs. waiting for a call forward through the cellular networks.

You can add a SIP contact on any of your Google contacts by revealing all fields when editing a contact. Once you show all fields, scroll down and you’ll find an entry for SIP. This will let you enter any SIP URI or just another extension on your corporate system.

We won’t try to reproduce all of the settings here, but you can head on over to the sipXcom Wiki to see how to configure the Android Dialer. We hope you give it a try and report back what you’ve found!

From 2010 to 2015, sipXecs primary development contributions were provided by the development team at eZuce, Inc. The sipXcom open source communications project was established in January of 2015 from a fork in the sipXecs project by the development team at eZuce, Inc.
