There are two ways that you can implement reliable faxing:
1) Implement end-to-end QoS and insure that latency is very low and there is no jitter. Should be 95% reliable, more or less depending on the quality of the link. Most people don't have the ability. It's not possible with ADSL, not technically but all the large carriers are moving away from dedicated PVCs, concentrated best effort is the best you get. T1 + LAN generally works well without any tweaking. Use ulaw for T1 alaw for E1, if you are sending to another VoIP provider you still need QoS. 2) Use T.38. Should be 99% reliable assuming that you have minimal jitter a decent amount of bandwidth and still latency below 250ms. Digium IAXY does not support T.38, Asterisk support in T.38 is generally lacking, unless you use 1.4 and send your calls to a SIP provider that supports T.38 you aren't going anywhere.

Can someone tell me how to get faxing to work with an IAX2 remote client? I have two customers both are connected via Digium's ATA's S101I both can place and receive calls without any problems. However when they connect there line to a fax machine it never connects to the remote fax machine. They place a normal POTS line and all faxes fine. Any light is appreciated. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
