Incoming calls are working, but I cannot make outgoing calls. whenever I try to I get “All Circuits are busy now” message. I followed the GXW410 guide
That old guide uses the obsolete chan_sip driver. If you updated to pjsip, please post your trunk settings.
At the Asterisk command prompt type
pjsip set logger on
or
sip set debug on
as appropriate, make a failing test call to 18004377950, paste the Asterisk log for the call at pastebin.com and post the link here.
thanks for trying to help, I solved the problem and will update that old doc.
