G.729 codec in linphone

Eric — Sat, 12 Nov 2016 10:32:39 -0500

Running Manjaro, I installed linphone along with all required libraries from AUR. The application works well except for the fact that the codec list is incomplete. The G.729 codec, for instance is not available.

The log file indicates a few problems:

ldconfig -p|grep 729

libbcg729.so.0 (libc6,x86-64) => /usr/lib/libbcg729.so.0
libbcg729.so (libc6,x86-64) => /usr/lib/libbcg729.so

Any idea as to why I need to do for G.729 to be enabled? Thanks for your help.

Add `voip` and `sip` tags

I'm not sure where else to ask for this, so here I go: Please add voip and sip tags. This would be useful for questions like: Error when configuring Linphone to use SIP (TLS)

Error when configuring Linphone to use SIP (TLS) and ZRTP encryption

landroni — Tue, 12 Aug 2014 05:51:32 -0400

I am trying to configure Linphone to wrap all media communications in an encryption layer (on Xubuntu). According to their website, Linphone supports:

Secure communications (TLS, SRTP, zRTP)

However, when I try to configure Linphone in Options > Prefs > Network Settings > Network protocol and select SIP (TLS) then Linphone immediately complains with the following error message:

Could not start tls transport on port 5060, maybe this port is already used.

Linphone works just fine when I switch back to SIP (UDP).

What is wrong and how can I fix it?
