Everything works fine but we have this extrange issue, when I use a softphone (Zoiper) from outside the office, conecting via VPN and try to make an external call we get no audio, the call is completed but no audio. The only diference is that this extension has PINLESS DIALING ENABLED, when I disable PINLES DIALING it works fine but obviously it asks for a PIN.
Can anyone explain me why?
Thanks
