This suggestion at the top means either:
(1) compile linphone for android from sources
(2) change any existing binary *.apk file: unpack *.apk, edit
"audio_rtp_port/video_rtp_port" values, repack *.apk, install on device
** Feature request for linphone-android: like in the desktop
application, add a possibility to change these port values into network
The problem is, if located behind a telco-provided DSL-modem which also
has built-in VoiP (e.g. Deutsche Telekom), one cannot make linphone
media stream connections any longer (using these default port numbers).
My linphone media streams stopped working the day I had to start using
Telekom-imposed VoiP. Telekom probaby uses the same-numbered RTP-ports
and hijacks any incoming media stream in the DSL-modem (possibly
erroneously, in end effect simply nuking any "foreign" incoming media
stream at these incoming ports). There is no way to reconfigure
anything in the black-box device provided by Telekom.
In an older linphone-android I managed to implement method (2) above as
proof of concept of the solution.
P.S. It was quite effortful to figure out what suddenly happened after
Telekom-VoiP was turned on. :-)
