Hi all, I want to use pure STUN solution (without TURN/ICE) in my platform and have some question about STUN in pjsip. (1) Does pjsip support refresher mechanism ? --------- For example, I hope to configure stun refresher timer to 60 sec. And stun client would send STUN binding request to server every 60 sec. It would re-register if it find the mapped-address has been changed. ---------- If yes, how to configure it? (2) How to support STUN over TCP/TLS ? As I know, pjsip support RFC3489 and RFC5389. RFC 3489 (Simple Traversal of UDP through NATs) is a complete NAT traversal solution. RFC 5389 (Session Traversal Utilities for NAT) is now a tool that can be used to produce a NAT traversal solution (Ex. TURN , ICE). If I only configure STUN (without ICE/TURN), can it support stun over TCP / TLS? For UDP case in pjsip, it would call pjsua_transport_create() --> create_sip_udp_sock() --> pjstun_get_mapped_addr2() to get mapped-address. But how to handle it by TCP/TLS ?Or it can only be handle by TURN and ICE ?? Regards, Terry
