Installation
Here is how to get the best possible experience of running VoIP on your N97 with what is currently available from Nokia with a few hacks and such. Hopefully when Nokia comes around to releasing an official package there will be more features available - but until then this is how to get SIP working.
Remove the old applications
Settings / Application mgr. / Installed Apps
Remove anything you may have installed. In the app manger under installed apps look for 'InternetAdvSetting' or anything that begins with 'SipSettings*' etc. Get rid of them both.
Install 'InternetAdvSettings' by Nokia
You can download the file here.

This file has been extracted from the latest 'SIP_VoIP_3_x_Settings_v2_0_en.sis'. This original file will not work as a standalone installer - but one of the parts within it solves the issues, we have supplied the extracted part for you.
Create your SIP profile
Settings / Connectivity / Admin Settings / Sip Settings / New Sip Profile
Name your Profile something you like, such as 'VOIP' - this will be the name it shows up under contacts. For example if you named it 'VOIP' when under a contact it will show as 'VOIP Call'. For a typical install see the bottom of this page. Set the Transport Type to UDP if calls are not working over 3G !
Create a VoIP Service
Settings / Connectivity / Net Settings / Advanced VoIP settings / Create new Serivce
In order to actually use the SIP profile created in Step 3 you must Create a VoIP service. To do this select 'Create new service' and then select the Profile you created in Step 2. This will add a new item under 'Net settings' if you named your profile 'VoIP' it will show up as VoIP Sett.
Adjust your Codecs
Settings / Connectivity / Net Settings / Advanced VoIP settings / Voip Servies / <your profile> / Codecs /
If you know that your SIP provider supports G.729 then move that codec up to be #1 in the list - this should be self explanitory. If you don't know what you are doing, skip this step!
Enable SIP over 3G
Connectivity / Net Settings / Advanced VoIP settings / Voip Servies / <your profile> / Profile settings
To enable SIP Calls over 3G set both 'AWCDMA' and 'UAWMAC' to ON. Note that you will be charged for data when using 3G - and your phone should warn you when doing so.
How to Start and Stop VoIP Service
Contacts / Globe Icon
To start or stop the SIP service enter contacts then see the newly created Globe Icon - select your SIP user name, hit 'Options' and either log in or log out. When the service is connected to the SIP Server you will see a phone sitting on top of a globe up on the status bar.
Setting up your SIP Profile
The following is how to set up your SIP profile. If you have the service running, you must stop it in order to modify it this can be done following bullet #7 above.
Settings / Connectivity / Admin Settings / SIP Settings / Options / New SIP Profile
