Once I compiled Asterisk version 13.13.1 and when running make I noticed the following error:
‘pjsip_tcp_transport_cfg’ has no member named ‘sockopt_params’
pjproject-2.2.1 has already been compiled.
Solved the problem by compiling a newer version of pjproject-2.4.5
cd /usr/src wget http://www.pjsip.org/release/2.4.5/pjproject-2.4.5.tar.bz2 tar -xjvf pjproject-2.4.5.tar.bz2 cd pjproject-2.4.5 CFLAGS='-DPJ_HAS_IPV6=1' ./configure --prefix=/usr --enable-shared --disable-sound --disable-resample --disable-video --disable-opencore-amr make dep make make install
After that, the error disappeared.
