I have been tasked with investigating the feasibility of writing an iPhone App to access our internal VoIP/SIP systems.
I've never coded anything close to VoIP before. Are there any open source VoIP/SIP libraries/examples in C or Objective-C?
An O/S iPhone App that I can skin and add our required features to (mainly UI related) would be the holly grail here.
You may take a look at siphon (http://code.google.com/p/siphon/).
From their homepage:
Home of the World's first free SIP/VoIP application for iPhone and iPod Touch 1 and 2.
Siphon SIP/VoIP project is the first in his category that works on iPhone and iPod Touch 2 with headset for all SIP providers. It is a native application approved running on 2.X using internal micro/speaker and headset.
The Application supports the SIP standard, preserving compatibility with hundreds of SIP providers and offers a GUI which preserves the apple design of native iPhone applications.
A colleague of mine wrote an Asterisk client, available on Github (http://github.com/pzion/miumiu)
From the project page:
MiuMiu is a VoIP application for the Mac and iPhone that uses the IAX protocol
Hi, Even I am looking for the same solution. with respect to siphon mentioned above it is and Open source GPL licensed and because of which i found problem in making use of the same in my Commercial application.
Is any SIP client or Application which i can use it in Commercial Iphone Application.
