Have FAXES ROUTED BY CALLER ID
suggestion to have FaxMaker route calls by caller id as well as CSID. This would solve faxes being transmited by senders which do not include CSID in their tranmisions.
Albert Bezzina commented
FaxMaker already supports this by using the following registry tweak:
KEY: HKEY_LOCAL_MACHINE\SOFTWARE\GFI FAX & VOICE\FAXmaker\Config
DESCRIPTION: If enabled (1) the user sender fax number will be used for routing in CSID.
