I have a customer site where we have a VG224 providing analogue ports for fax machines/franking machines and modems. All using G.711 passthrough direct to the PSTN gateway.
Fax machines work no problem. Franking machine works no problem. Outbound modem calls work better than expected. They actually connect at 52.0Kbs second.
However, one of the modems has to recieve calls from a central security function to access the cctv application that runs on a standard Dell PC running Windows XP. Outbound call from the PC to the internet works fine connects 52.0Kbs. When we attempt to dial into the PC the orginating modem states it doesn't get a carrier signal. The modem log on the receiving PC indicates that the call connects then drops within milliseconds stating no carrier.
I have been running various debugs on the VG224 which shows it connects but I cannot determine what is happening next. a debug voip hpi all appears to indicate that the VG224 is seeing CM tones and Modems tone but I cannot determine from where these tone are coming from.
Does the VG224 need some specific configuration when receiving modem calls as oppose to initiating them.
