Hello. I just started using 3CX brilliant software. when I try to use it with internetcalls.com SIP all works well. I can call with a success and great sound quality to stationary phone numbers in norway and Poland. I have also Norwegian Phonzo as my VOIP/SIP provider. I put all settings, and then I can't make outgoing calls. I can receive calls and call to mobile cellphone numbers, but when I try to call stationary numbers in Norway or Poland, I just can't. It says calling and then calling stops after 10 sec. Any idea what is wrong?
