Making VOIP calls using only G.729 codec in iphone

Question

This is my first VOIP application.

I am using linphone source code which I downloaded from here and I am able to make calls using speex audio codec but i want to make calls using only g.729 codec. I enabled g.729 codec in my code by following this link

But when I try to make call using Only g.729 codec then it is giving error media not supported.

Any help is appreciated.

Please help me in solving this.

Thanks

I have achieve that after the flowing step:
1. Build your linphone lib with G.729 codec
2. Load G.729 codec in factory config (code)
3. Set G.729 as default codec (optional)
