Problems with Microsoft Fax (XP and 2000)

[vlanze]

I have this problem where I was not able to send or receive using Microsoft Fax (for WinXP and 2000). I'm using a GPRS modem which I have got working for other fax softwares like Symantec and MightyFax.

 

I was able to establish a connection but was not able to send or receive. I can hear the ringing sound from the remote fax machine I was dialing but no fax was received there. Error message is "An error occurred while sending/receiving fax".

 

For Win2000, I was only able to send but even then, the fax was not clear. Help appreciated. Thanks.
