We were looking through SIP and we would like to have the minimal code possible to register, make a call and answer a call. We would like to not use any unnecessary libraries or files. 1) Is there a place where we can start to take out such unnecessary code? We are looking at this : http://www.pjsip.org/pjsip/docs/html/page_pjsip_sample_simple_pjsuaua_c.htm This is ideal but this has pjmedia related dependencies (in pjsua.h which has pj-mediacodecs refs). If this was a self sufficient package which just handles this stripped down functionality that would be great. 2) we would like to avoid using third party libraries completely and just use our own c code to make calls, answer and register. Are there some pointers or hints in pjsip or some resource on the web? -- Shiraz 500 Riverside Drive #425 New York, NY 10027 (703) 879-8342 (skype prefer) (571) 276 2404 (cell) (212) 316 8630 (landline) (extn 8630)
