How to Build and Test PJSIP 2.5.5 for IOS with IPv6 Support

Question

I am using pjsip 2.5.5 for my project. enabled IPv6 support by adding #define PJ_HAS_IPV6 1 in pj/config_site.h. following ( https://trac.pjsip.org/repos/wiki/IPv6 ).

With this I made build for linux and mac. build succeed and I tested by calling PIN to PIN (using --ipv6). It is working fine for IPv6 Addresses.

Now I made build for IOS and testing it in simulator using cli(telnet). while checking account list using show (l) [for complete list of commands refer: https://trac.pjsip.org/repos/wiki/PJSUA-CLI?format=pdf ] . It is showing only IPv4 accounts (UDP and TCP), NO IPv6 Accounts.

Where I am going wrong?

Is there any flag need to define?

How to test pjsip build with ipv6 for IOS using pjsua?

You need to create both the transport at the same time like below.

/* Add UDP transport. */
status = pjsua_transport_create(PJSIP_TRANSPORT_UDP, &app_config->udp_cfg, 
&transport_id);
if (status != PJ_SUCCESS) {
    goto error;
}

/* Add UDP6 transport. */
status = pjsua_transport_create(PJSIP_TRANSPORT_UDP6, &app_config->udp_cfg, 
&transport_id);
if (status != PJ_SUCCESS) {
    goto error;
}

For TCP and TLS you also need to do same as above.

Happy to help all :)
