I'm using Liblinphone (belle-sip/1.4.1) and Pjsip 2.4.5 I verified that the two do the same thing. I'm doing that on my phone the option of -p is not available but I'm able to change the 5080 and 5070 from inside the library manually and I'm using port 443 for TLS not 5061 and there just a random port 48110 that got changed every time I open the app. I'm pretty sure that all these belong to the app. They come with the app and go when exiting the app.
I don't know the other random port is used in SIP communication or not, but it's the same number of connections with the two libraries pjsip and liblinphone. On Tue, Nov 3, 2015 at 5:56 AM, Dale R.
