Or how to get my Dial(SIP/...) working? I am new in Asterisk. All other Asterisk tests worked, exception is Dial(SIP/.. My setup: ADSL NAT Router has UDP ports 5060 to 5070 and 8766 to 35000 forwarded to 192.168.254.1 On 192.168.254.1. Linux system from sources. Asterisk 1.6.2.1 I know that there are codecs missing. Adjusted sip.conf accordingly. Registering myself (with "register =>" in sip.conf) to ekiga.net succeeded too. sip.conf: [general] context=default allowoverlap=no udpbindaddr=0.0.0.0 tcpenable=no tcpbindaddr=0.0.0.0 srvlookup=yes sipdebug = yes qualify=yes externip=195.241.23.211 localnet=192.168.254.0/255.255.255.0 nat=yes [basic-options](!) dtmfmode=rfc2833 context=from-office type=friend [natted-phone](!,basic-options) nat=yes directmedia=no host=dynamic [2131](natted-phone) secret = ****** disallow=all allow=g729 allow=gsm allow=g723 allow=ulaw extensions.conf: [general] static=yes writeprotect=no clearglobalvars=no [globals] ; all until and including [default] from make samples [default] include => demo [from-office] exten => 1020,1,Dial(SIP/500 at ekiga.net) include => default On 192.168.254.2 Linux from sources with Ekiga 3.2.6 succeeds registering as [2131]. Demo, IAX, echo and console tests passed. But never got SIP working from Ekiga. No errors in /var/log/messages On www.tjoen.dds.nl/asterisk.log the output of # asterisk -vvv with only one attempt to dial 1020 Looks like the "line" is busy? Or an error in my setup? Do I need something more to get SIP working?
