OK I found the reason. I just used the sample code here,
/* Add TCP IPv6 transport unless it's disabled. */
if (!app_config.no_tcp && app_config.ipv6) {
pjsua_acc_id aid;
pjsip_transport_type_e type = PJSIP_TRANSPORT_TCP6;
tcp_cfg.port += 10; /* b/c for v4 I set tcp_cfg.port = 0, so here it will 10! */
So can I also set tcp_cfg.port = 0 here ?

I do’t want to set it to specfic port and that was why I set to 0 in the first place. Beside it only happened to ipv6

Try to set the default port to 5060, or increase it to 5070 in the case of failure.

If only happened to ipv6, ipv4 does not have this problem. And of course I set app_config.udp_cfg.port = 0 to let pjsip choose any available port.So any idea why and how to fix it ?Thanks,Qiulang
