Hello,
I have been trying to get the windows desktop app to work as I have it installed on a PC with Windows Vista Home Premium as this seems to be only way to test it out prior to buying a SIP unlock key and ATA. I can make an outgoing call using the desktop app and make a call to my mobile phone. However, there is no audio in either direction.
I have disabled the SIP ALG on both my ISP modem running in bridge mode and my router.
Can you suggest what may be the issue and help me resolve this problem?
Thanks in advance.
