I have been unable to get the incoming FAX working.... I think I have now found out why (that or I am about to look very silly) We run with a 4 digit extension profile for the Fax is configured as default to 8888 When I look in the logs, the FAX client is registering as 888 This login info the client gets from the public_prstorage table in the 3CX database. All other entries for SIP ID's are updated correctly to the 4 digits except the FAX client.... Bug?, looks like it to me..!!! I have tried editing the entry via an ODBC connection from Access but the record in not updateable.... Anyone got any ideas?
