[mtsai at sunrisetelecom.com]

Hi all,
 
I am looking for C or C++ SIP client open source codes, with the following consideration. Please kindly provide analysis (pros and cons), suggestions. Thank you in advace.
 
1. Organized, easy to understand, well-documented.
2. Easy to integrate with different CODEC's.
3. Easy to modify code to be able to inter-operate with proxies and UA's of various venders.
4. Easy to change the behaviors of the stack. For exmaple, use TCP or UDP, change CODEC priorities, specify jitter buffer parameters...etc.
5. Easy to add customized features on top of the stack.
6. Easy to obtain updates and bug fixing.
7. Portable to different OS.
8. Support SIP applications: IP calls, presence, instant messaging, ...etc.
