Hi, I foundpj_sock_bind sometime failed for ipv6 with the error message "pjsua_core.c Error creating SIP TCP listener: Address already in use [status=120048]“. If only happened to ipv6, ipv4 does not have this problem. And of course I setapp_config.udp_cfg.port = 0 to let pjsip choose any available port. So any idea why and how to fix it ? Thanks, Qiulang

Try to set the default port to 5060, or increase it to 5070 in the case of failure. > On 13 Sep 2016, at 09:59, qiulang <qiulang@emicnet.com> wrote: > > Hi, > > I found pj_sock_bind sometime failed for ipv6 with the error message "pjsua_core.c Error creating SIP TCP listener: Address already in use [status=120048] “.
