Welltech FXS gateways

Welltech produce a range of analogue gateways that offer excellent voice quality and fax support.  The details on this page relate to the WellGate 3504a 4 port FXS gateway (H.323 version) and should result in the best quality when used in conjunction with the DUAL Talk VoIP service.  For initial testing, place a call to 123 and confirm that you hear a test announcement.

H.323 configuration

Fixed IP address (use these settings if your IP address is fixed by your ISP)
  • Make sure the IP address you use has been added to your DUAL Talk account.  If you did not add this address while setting up your account, then add this IP address at the Access Methods area of My DUAL Talk; the online account management system.
  • Mode  =  Peer-to-peer
  • Default Gateway IP  =

Dynamic IP address (use these settings if your ISP regularly changes your public IP address)
