Sipdroid is a mobile internet service that enables you make calls using your cell phone's internet connection. You download sipdroid to your mobile device and then configure it for OnSIP Hosted PBX. Once configured, you will be able to dial extension to extension calls within your PBX as well as make calls to the PSTN all over your cell phone's WIFI connection. Additionally, you will be able to receive calls to your mobile device when someone dials your extension (assuming that sipdroid is up and running on your phone and you are on a wifi network).

Please Note:
-Transfers to DIDs and extensions do not work as of the 1.4 beta due to violation of SIP RFC 3261 (formatting of the Request-URI) must be sent in the <did>@<domain> format, as opposed to other SIP user agents that auto append the domain for you. Transfers to SIP addresses function correctly.

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

You can find this information in the user detail pages under the Users tab in the Phone Configuration section.

Step 2: Download Sipdroid from the Droid Market.

From the home screen, touch Market --> Search.
Search for Sipdroid, highlight it and click "Install".

Step 3: Configure OnSIP Hosted PBX user account information.

Touch Settings --> SIP Account Settings

SIP Account Settings

  • Authorization Username > Auth Username
  • Password > SIP Password
  • Server>
  • Domain> Domain
  • Username/Caller ID > Username
  • Port > 5060
  • Protocol > UDP

If the account successfully registers, you'll see a small green dot in the upper left.

Step 4: Configure Sipdroid to use the WLAN.

Touch Settings -> Call Options and check "Use WLAN". Our experience was that call quality was unacceptable over the 3G network, so we also unchecked "Use 3G". If both are checked, Sipdroid will only use the 3G network if the Wifi network is unavailable.

Step 5: Enable the appropriate codecs.

Touch Settings -> Audio Codecs.
Change speex to "never", alaw to "never" and ulaw to "always try".


If you are experiencing trouble, double-check your settings as described above and be sure to verify that your password was entered correctly without any leading or trailing spaces. If you are still having problems with your phone configuration, please see our troubleshooting section for further help.
