Archived:IMS registration using Symbian C++
Which is the best and easiest way to make a valid and compliant IMS Registration (REGISTER METHOD) from a Symbian C++ application on Nokia S60 3rd Edition phones?
Register the profile using the SIP profile APIs. The profile would be in IMS/3GPP mode and, when enabled, will register as per the IMS specification. It should be able to showcase this in the current SIP example application (available in SDK examples under \S60Ex\SIPExample).
