Does anyone try to connect a Multivoip Gateway MVP130-AV FXS in an IP Office? I connect a Multivoip in an IP Office with VCM and automatically recognize it as an H.323 device and creates an IP extension. Then I connect an analog phone in the fxs port of Multivoip and I manage to dial the extensions in the IP Office. The extensions are ringing but when you answer nobody can hear each other. Does anyone knows what is the problem?
