[cisco-voip] UC500 Analog Faxes on fxs ports configured with stcapp

[Anthony Kouloglou]

Hi,
i am back to this.
It didn't work also!
I simplified the config with h323 config but still, faxes could not be 
received!
I noticed that the UC was up for 30 weeks so i reloaded it.
Ever since then, no problem exists on receiving faxes!!
uc is running:flash:uc500-advipservicesk9-mz.124-24.SB
is this known bug?
What could have caused it?
