hi,

i have following topology

PSTN - Asterisk ---- internet -----  router - jssip client (wss)

Asterisk 13.29.1 on public IP, chan_pjsip for wss, chan_sip/udp for SIP connection to PSTN

router - public IP/private IP (NAT)

jssip client - private IP - sip over websocket to Asterisk PJSIP


~30% of calls has problem with no audio. reason is that Asterisk is sending RTP to private IP of jssip

SDP looks the same for good call and bad call too


i searched through res_rtp_asterisk.c but i'm not sure where to put DEBUG info about which IP and why Asterisk pick for RTP

any hint?


is it possible debug Asterisk STUN request/response ? or is it hidden in pjsip internals?


Marek
