Adding PBXes.org to Nokia N95

So you want to use your Nokia N95 with the popular PBXes.org service to start using VOIP calls, you have come to the right place. Note that these instructions will most likely apply to all Symbian S60 phones, like the Nokia E65. Also note that in case of the N95, this even works for phones without a SIM card, making it possible to call with those phones as well!

In this article I assume that you already have a PBXes.org account and have set up an extension for your Nokia N95, if not please look at this guide.

Let create the SIP profile to connect to PBXes.org:

  1. Open the menu.
  2. Open “Tools”.
  3. Open “Settings”.
  4. Select “Connection”.
  5. Scroll down and select “SIP Settings”.
  6. Click “Options”.
  7. Select “New SIP profile”.
  8. Select “Use default profile”.
    1. Change the profile name to something familiar: “PBXes.org”.
    2. Leave “Service Profile” at “IETF”.
    3. Set “Default access point” to your current Wifi network
    4. Set “Public user name” to “This email address is being protected from spambots. You need JavaScript enabled to view it.” where you substitute “myuser” for your account name and “800” for the extension number you created for this phone.
    5. Leave “Use compression” on “No”.
    6. Set “Registration” to “Always on” to force the phone to connect to the SIP service when starting up (or leave it if you are not planning on using it all the time).
    7. Leave “Use security” on “No”.
    8. Leave “Proxy server” empty.
    9. Enter “Registrar server”.
      1. Set “Registrar server address” to “sip.pbxes.org”.
      2. Set “Realm” to “pbxes.org”.
      3. Set “User name” to “myuser-800” and substitute like before.
      4. Set “Password” to the password you set on pbxes.org for this extension number.
      5. Set “Transport type” to “UDP”.
      6. Leave “Port” on “5060”.
      7. Click “Back” to return.
    10. Click “Back” to return to “SIP Settings”.
  9. Click “Back” to return to “Connection”.
  10. Select “Internet tel”.
  11. Click “Options”.”
  12. Select “New profile
  13. Change the name if desired.
  14. Select the SIP profiles to use, if you only added PBXes.org it will be selected by default.
  15. Click “Back” to “Internet telephone”
  16. Click “Back” until you reach the “Tools” menu.
  17. Select “Internet tel”.
  18. Click “Options”.
  19. Select “Connect to service

The phone will now connect to the Wi-Fi network you specified earlier and a globe with phone icon will appear showing that the registration was successful. When you want to call using the SIP account, use “Options” and “Internet call” to activate the SIP mode.

To switch to SIP calling by default do the following:

  1. Open the menu.
  2. Open “Tools”.
  3. Open “Settings”.
  4. Select “Phone”.
  5. Select “Call”.
  6. Scroll down and set “Default call type” to “Internet call

Next time you will call a number it will use your SIP account automatically! (Note: if the SIP account fails – no Wi-Fi etc – the phone will switch back to normal calling modes).

Common pitfall: “Address not in use” when you try to call a number (meanwhile you can receive calls fine). This happened to me because I did not specify a Default route for the newly added extension, after making the standard route truly global all was well.
