just tested call duration over 5 mins and successfully placed a call for 6 mins (you owe me 9 pence
) using the details you posted.
I am still unable to receive incoming calls 'your call cannot be completed at this time in the country you are calling'. I tried with and without the firewall on.
If I try context = from-internal instead of from-trunk then in the call log a see a call with the source and destination being sipgate phone number. Still nothing rings, If I now turn off the firewall the cell phone (that I am calling in on) has ringing tone but no internal LMCE phone rings.
