CSIPSimple Softphone for Android

This is available for information only- CSipSimple is no longer being developed (since 2017)- no further support is available.

Step 1: Gather information for each user.

Each user has a set of credentials which will be needed to configure each phone. For each phone that you are configuring, obtain the following:

  • SIP Address (Address of Record)
  • SIP Password
  • Auth Username
  • Username
  • Proxy/Domain
  • Outbound Proxy

You can find this information in the user detail pages under the Users tab in your OnSIP Admin Portal.

Step 2: Download CSIPSimple from the App Store.

Step 3: Configure OnSIP Hosted PBX user account information.

When you start CSIPSimple for Android for the very first time, it should automatically take you to the ‘Account’ screen. If this is your first SIP account, you should see a setup wizard that looks something like the first image below. Enter in your credentials in the fields on these pages as follows:
