Alcatel Unleashed

Have sip gateway setup with analogue phone and analogue fax.

Can make phone calls internally / externally.

Can send fax'es internally..... But when I try to send fax'es outside the organisation I get "comm error" on the fax.
I am now pulling my hair out trying to fix this. Does anyone have any ideas why?
I have tried trunk sieze on all manner of different trunks. ISDN Dass Analogue.
Not sure if this would be an issue but the analogue line I tried was an NTL line (would this be an issue)?

Thanks

I know that fax over sip does not work properly until R7.1. I was having the same problem on R 7.0 but when upgrading to 7.1 it started working.

regards

THis feature is only support since R7.1. Regards.
