Here’s the set of instructions to setup SIP/VoIP calls on your Nokia E-series device.

I have used E71 device and Jumblo as SIP provider for my setup but you can use any provider of your choice.

First go to Settings->Connection->SIP Settings and create a new SIP profile from options. (Please follow instructions properly otherwise you may received “Unable to register” error).

Profile Name : Jumblo (user friendly name for your profile – you can choose any)
Service Profile : IETF
Default access point : myhome (Your wifi or 3g access point)
Public user name : myusername@sip.jumblo.com (username which you have created with your SIP provider)
Use compression : No
Registration : When needed
Use security : No

Proxy Server

Proxy server address : sip.jumblo.com
Realm : sip.jumblo.com
User name : myusername (username which you have created with your SIP provider)
Password : yourpassword
Allow loose routing : Yes
Transport type : UDP
Port : 5060

Registrar server

Registrar server address : sip.jumblo.com
Realm : sip.jumblo.com
User name : myusername (username which you have created with your SIP provider)
Password : yourpassword
Allow loose routing : Yes
Transport type : UDP
Port : 5060

If you received “Connection error”, please follow these steps.

Go to Settings->Phone->Call and set “Send my internet call ID” to “Yes”. This should solve connection error issue.

Note : SIP uses port 5060 to make calls, if your ISP has blocked that port (few countries have that port blocked) then you won’t be able to make call even if you have configured it correctly.
