When I dial from my ATA to a PSTN phone or from a PSTN phone to my ATA I can hear the phone ringing from both ends. The problem is when I use IP dialing to dial from my ATA to another VoIP account. From the phone on my ATA only two rings are signaled. From the other end all rings are heard. On my phone I should receive a sound for each ring on the other part. Can this problem be resolved?
Thanks in advance.
