Outgoing calls rejected b/c extension not found?

Hello,
I am new to Asterisk - running it on a ASUS N66U.

[code]OS Version:
Linux RT-N66U 2.6.22.19 #4 Sun Jul 7 01:51:55 EDT 2013 mips GNU/Linux

Asterisk Build:
Asterisk/1.8.10.1
Asterisk GUI-version : SVN–rexported[/code]
The ASTERISK installation is not behind NAT.

I have incoming calls working, but get an error I don’t quite understand doing outgoing calls - 070XXXXXXX is my cell phone number;

Is it looking for a local extension instead of transfering the call to my registred SIP-trunk?

Here is the output of SIP debug on outgoing call;

Could the “SIP/2.0 404 Not Found” be my problem, or is it just a secondary symptom?

Very thankful for any help or hints to get me in the right direction.

Best regards,
Federico

The 404 is secondary; it is how SIP UAS’ report it to the UAC.

Your sip.conf has matched and entry which has context=DLPN_Default. That context, in extensions.conf either doesn’t contain such a context, or there is no exten => xxxxx,1,… line in that context where xxxxx is, or matches 070XXXXXXX. sip.conf includes the transitive closure of all files included from it, and any entries introduced by Asterisk realtime. Similarly for extensions.conf. The context includes any contexts included by include => lines.

Thank you for your reply - I could fix it by manually editing the extensions.conf.

Still not getting out though;

The only thing resembling an error I can find is this;

[code]SIP/2.0 401 Unauthorized

SIP/2.0 404 Not Found

SIP/2.0 503 Service Unavailable

SIP/2.0 500 Server Internal Error[/code]

I also switched to a more modern client - Siemens C610 IP - but that made no difference.

Really grateful for any feedback.

bahnhof-lda.soho1.voip.bahnhof.net doesn’t consider 0708XXXXXX to be a valid num ber.
