Hi all, my Asterisk 1.6 is connected via FritzBox (NAT) to [sipgate.de](http://sipgate.de) Register is possible but no incoming and no outgoing calls are possible 1. Problem: incoming calls (from external) I installed SJphone and compared both sniffer logs (from SJphone and Asterisk register): SJphone: Via: SIP/2.0/UDP 192.168.x.x;rportbranch=blabla Asterisk: Via: SIP/2.0/UDP 93.200.x.x;rportbranch=blabla Since Asterisk is behind NAT the internal IP should be used here as well, shouldn’t it ? (currently using the official IP from my FritzBox) 2.Problem outgoing calls (to external) If trying to call any external number (e.g. testnumber 10005 from sipgate) I can see the following message in CLI: called [10005@sipgate.de](mailto:10005@sipgate.de) Failed to authenticate on INVITE “USER1” sip:501@217.10.79.9 Well - of course [sipgate.de](http://sipgate.de) doesn’t know my user 501… I’m pretty sure both problems are caused by misconfiguration, but I can’t find where. sip.conf ```auto [general] context=general useragent=Asterisk PBX bindport=5080 bindaddr=0.0.0.0 language=de disallow=all disable=all allow=alaw allow=ulaw allow=g729 allow=gsm allow=slinear srvlookup=yes nat=yes ;externhost=asterisk.dyndns.org externip=93.200.x.x:5080 externrefresh=180 localnet=192.168.178.0/255.255.255.0 ;stunaddr=stun.sipgate.net:10000 host=217.10.79.9 register=>:@sipgate.de/ ;register=>:@217.10.79.9/ canreinvite=no dtmfmode=rfc2833 qualify=yes fromdomain=217.10.79.9 [sipgate] type=friend username= fromuser= host=dynamic disallow=all allow=alaw allow=ulaw allow=gsm context=meine-telefone outgoingproxy=sipgate.de nat=yes [200]; Hausmeister type = friend callerid="Hausmeister Krause"<200> context = meine-telefone secret = 1234 host = dynamic ``` extensions.conf ```auto [general] [meine-telefone] include => sipgate exten => _9.,1,Dial(SIP/${EXTEN:1}@sipgate.de,30,r) exten => ,1,Ringing exten => ,2,Wait,2 exten => ,3 Dial(SIP/200,20,tr) exten => ,4,Hangup ;Hausmeister exten => 200,1,Dial(SIP/200,5) exten => 200,2,VoiceMail(200,u) exten => 200,2,VoiceMail(200,b) include => voicemailsystem ``` Thanks a lot in advance ! ---

Hi Basicly you are just sending the number straight to sipgates server with no auth at all have a look at their german site for german langague version but heres the english version [general] port = 5060 bindaddr = 0.0.0.0 context = sipout qualify=no disallow=all allow=alaw allow=ulaw allow=g729 allow=gsm allow=slinear srvlookup=yes register =\> [SIPID:PASSWD@sipgate.co.uk](mailto:SIPID:PASSWD@sipgate.co.uk)/SIPID [sipgate-out] type=friend insecure=very ; otherwise I get authentication errors nat=yes username=SIPID fromuser=SIPID [fromdomain=sipgate.co.uk](http://fromdomain=sipgate.co.uk) secret=SIPPW [host=sipgate.co.uk](http://host=sipgate.co.uk) qualify=yes canreinvite=no dtmfmode=rfc2833 # extension.conf [sipout] exten =\> \_X.,1,Set(CALLERID(num)=SIPID) exten =\> \_X.,2,Dial(SIP/${EXTEN}@sipgate-out,30,trg) exten =\> \_X.,3,Hangup Ian ---

Thanks for your reply ! I did now adapt the extensions.conf to match your’s ```auto exten => _9.,1,Set(CALLERID(num)=) exten => _9.,2,Dial(SIP/${EXTEN}@sipgate,30,trg) exten => _9.,3,Hangup ``` callout-test Phone device connected to Asterisk claims “unavailable” in display and in CLI I can see: app\_dial.c:1502 dial\_exec\_full: unable to create channel of type ‘SIP’ (cause 20 - unknown) == Everyone is busy/congested at this time (1:0/0/1) blabal The Invite looks good now (so userid@ip) I’m still doing something wrong. Any idea ? THanks ---

Have you corrected your sipgate peer? as it stands yours is incorrect. ---

😕 I can’t see the wood for the trees (spent already the half night with this problem) What exactly shall I correct ? ---

Ok the easy opting is create a peer called sipgate-out [sipgate-out] type=friend insecure=very ; otherwise I get authentication errors nat=yes username=SIPID fromuser=SIPID [fromdomain=sipgate.de](http://fromdomain=sipgate.de) secret=SIPPW [host=sipgate.de](http://host=sipgate.de) qualify=yes canreinvite=no dtmfmode=rfc2833 and then the dial string as exten =\> \_9.,1,Dial(SIP/${EXTEN}@sipgate-out,30,trg) exten =\> \_9.,n,Hangup and see how that goes. ---

I solved the issue with the incoming calls in the meanwhile (at least it rings at extension 200, no idea yet how to make it possible to let the caller add the desired extension, but this will be another problem). Regarding the outgoing calls. in CLI I get callled 910005@sipgate SIP/sipgate-082360f0 is circuit-busy …handle\_request\_invite: Call from ‘501’ to extension ‘1005’ rejected because extension not found my configuration after the mentioned changes: sip.conf ```auto [general] useragent=Asterisk PBX bindport=5080 bindaddr=0.0.0.0 language=de disallow=all disable=all allow=alaw allow=ulaw allow=g729 allow=gsm allow=slinear srvlookup=yes nat=yes externhost=asterisk.dyndns.org externrefresh=180 localnet=192.168.178.0/255.255.255.0 ;stunaddr=stun.sipgate.net:10000 host=217.10.79.9 register=>:@sipgate.de/ canreinvite=no dtmfmode=rfc2833 qualify=yes fromdomain=217.10.79.9 [sipgate] type=friend insecure=port,invite nat=yes username= fromuser=>user> fromdomain=sipgate.de secret= host=sipgate.de qualify=yes canreinvite=no dtmfmode=rfc2833 context=sipgate-in ``` extensions.conf ```auto [sipgate-in] exten => ,1,Dial(SIP/200,20) exten => _X.,2,Hangup() [general] [meine-telefone] ;exten => _9.,1,Set(CALLERID(num)=) exten => _9.,1,Dial(SIP/${EXTEN}@sipgate,30,trg) exten => _9.,n,Hangup ``` ---

ah this is solved now. my extensions.conf was buggy. I changed it to ```auto [meine-telefone] exten => _X.,1,Dial(SIP/${EXTEN}@sipgate,30,trg) ``` And outgoing calls are possible now. Also incoming. Great support, Ian! Thanks you very much - you made my day 😄)) PS: remaining problem is to make it possible to dial any extension from outside (not only 200)
