Hi, We are looking at consolidating our lines with PRI. This will allow the elimination of many fax lines. Some of them will be replaced with this type of config ... PRI * IAX * Channel-Bank FAX We will have daggressor suppressor enabled. Is anyone doing this and should I expect smooth operation?

From what I have heard packetizing fax does not work well, does not matter if it is IAX or SIP. I think that was straight from digium tech support.

I think the real solution is some piggy backed protocol that can be told this is fax information at one end, digitize the fax as if it were a faxmodem, stream it to the other end using a non-realtime protocol, and then initiate a fax call at the other end and restream out the data, all while possibly holding open the original call to indicate reception confirmation at the end.

You should be able to packetize your fax calls without any problems. We have hundreds of fax and modem lines on MGCP IADs that connect to PRI gateways without problem, although I haven't tried with IAX. Be sure to use G.711 codec and disable echo cancellation, and if your network is robust with low latency and jitter, you should be fine. Brian -------------------- Brian F.

Some people run fax over IAX using ulaw codec on the local LAN. Martin On Thu, 3 Apr 2003, Brian J.

I have to disagree here. I send and receive faxes over IAX all the time James On Thu, 3 Apr 2003, Brian J. Schrock wrote:> From what I have heard packetizing fax does not work well, does not > matter if it is IAX or SIP. I think that was straight from digium tech > support. >
I too. We have a telco provider that brings analog lines by SIP (converted to analog by a cisco router in our office) And we have a standard fax running on that line.... so... remote FAX - GW -..sip..- CiscoGW - our fax Matteo.

James,> I have to disagree here. I send and receive faxes over IAX all the timeWhat echo_cans are you using on each end and do you have daggressive suppression enabled (one or both ends)? John This e-mail was scanned and found clean by Monroe-Woodbury CSD Antivirus.
