I am looking for a good open source project for my IAX application and couldn't found a good sample project for making and receiving calls with IAXClients and Speex Codec in Objective C.
I have downloaded [url removed, login to view] an Open source project which was uploaded 4 years ago. I tried to make it compile and work with IAX protocols and authentication with Asterisk.
But I am having a poor quality outgoing voice although Incoming voice is somehow better. My main concern is how can I improve voice quality for outgoing for calling party voice on receiver end.
I tried reading Speex library and somehow manage to improve but now my application is sending a delayed voice.
I also tried download TabikPhone [url removed, login to view] which was last updated an year ago. But I am unable to register for IAX nor SIP after uncommenting IAX from constant.h, and I tried some clients build on TabikPhone and they are also having delayed voice.
Therefore I am unable to find a good source for Objective C for IAX Client.
Miumiu is using an open source IAX Client, whose wrapper in JAVA for Speech is very good for Android.
Tabik is using an open source IAXComm client.
And source code for both can be download from the links mention above. I will make payment immediately after testing ipa file for the project, if it suits my requirement for good voice quality for incoming and outgoing calls without delay. Please keep in mind that I am not looking for SIP Client but addon will be an added advantage.
Then I will be need for source code and will make the payment.
