asterisk users - Jun 2003 - Fax and SIP

Hi list,

	I have the following scenario, and want to know what I have to do to transmit
faxes trought this link:

|cisco-ata186|----sip-----|asterisk|-------E&M alaw link-----PSTN

	The codec used is g711a.
	When I try to transmit a fax I receive a "TX FUNCTION WAS NOT
COMLETED" on the fax machine connected to cisco ATA186.
	Could someone help me?

thanks
Eduardo

Hi there,

I have made this setup work without any special modifications. I expect it 
raises some strict requirements on the latency of your IP network, so that 
might be an issue.

|cisco-ata186|----sip-----|asterisk|-------E400P PRI -----PSTN

The IP network was full blast 100Mbit/s with one router inbetween.
