We are having problems with outbound faxes with a fax machine connected to FXS port of a UC520.
Outbound faxes are received on the receiving machine as "half pages". Inbound faxes are received correctly.
We have replaced cables and tried with 3 different fax machines but the problem stays the same. We allso checked the configuration for network-clock settings but this settings are ok.
network-clock-participate wic 1
network-clock-select 1 BRI0/1/0
When the system is rebooted, all fax sending/receving works fine for a while, but the problem keeps recurring after a few hours.
I don't know where to search further for a solution on this.
Any help would be greatly appreciated!
