Hi All - I am playing with SIPML5. I was getting an error about wss.... I fixed that by doing : cat privkey.pem > asterisk.pem cat fullchain.pem >> asterisk.pem with my letsencrypt certificate. and setting tlscertfile=/etc/letsencrypt/live/mypath/asterisk.pem But now when I use the https://www.doubango.org/sipml5/call.htm and I click Login... I get this error on asterisk /var/log/asterisk/messages [Sep 27 14:58:08] NOTICE[46486] chan_sip.c: Registration from '"SIPMl5"< sip:jerry.geis at somewhere.com>' failed for 'IP:37994' - Wrong password my sip.conf entry is this: [jerry.geis at somewhere.com] type=friend defaultname=jerry.geis at somewhere.com defaultuser=jerry.geis at somewhere.com secret=(matches that on the website page) encryption=yes avpf=yes force_avpf=yes dtlsenable=yes dtlsverify=fingerprint dtlscertfile=/etc/letsencrypt/live/mypath/asterisk.pem dtmfmode=RFC2833 host=dynamic description=Test context=sipml5 qualify=yes rtptimeout=60 rtpholdtimeout=60 rtpkeepalive=60 callerid="Jerry.Geis" qualify=no canreinvite=yes timezone=1 nat=force_rport,comedia disallow=all allow=ulaw allow=alaw allow=gsm Not sure what I dont have that is not accespting the PW. I am using 18.6.0 and still on the OLD chan_sip.c (which is working fine for everything else). Thanks Jerry -------------- next part -------------- An HTML attachment was scrubbed...
