Can not build app with this module

Hi @farfromrefug . I know it's been a long time since you've updated this but I figured I'll try my luck. I added this module in a test project but I kept on getting a Build error when trying to run the project in a simulator. COuld you help me.

[ERROR] : *\* BUILD FAILED **
[ERROR] : The following build commands failed:
[ERROR] : Ld build/Debug-iphonesimulator/TestSip.app/TestSip normal i386
[ERROR] : (1 failure)

This is for a proof of concept project. We target both iOS and Android thats why I went for a crossplatform tool like titanium for prototyping. I think this is the only available SIP module for iOS .
