Sorry for the late reply but both of these are fine, we use spandsp to print some faxes and email others. We also route via a PRI to our other phone system to hylafax on an analog modem and also to an analog fax. So what you want to do is fine and will work.

I have the same problem, Switched to HylaFax and IAXModem and had MUCH better luck. MUCH better being defined as not a single usable fax to only missing about 1%. Not bad. Spandsp or rather RXFax works on a few machines I hae quite well but on others it does not work at all, I have had good retruns with the HylaFax.IAXmodem combo on machines that could not use the RxFax. ________________________________ From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Tom Christensen Sent: Friday, May 19, 2006 12:18 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] FAX over PRI I have had nothing but problems receiving faxes over PRIs with spandsp.

We get the occasional bad fax, but it really is an occasional one, other than that, it's fine. We don't get any CRC errors or clock slips on the PRI, I'd certainly say that it would be a good starting point to check the counters on these, I'd also check that your drives are using DMA depending on your hardware, we had a customer a while ago who ended up doing a self install and none of his drives were enabled for DMA.

My failure rate, objectively measured, is 3.8%, and this is with 100 - 400 a day. Other than clock slips (which definitely adversely affects fax) I also note that load is an issue. A system with a higher load has a higher probability of failing the fax. Unfortunately, I don't have precise numbers, as I have gotten a feel for this by watching 2 SSH windows to the same box, 1 running top and the other running the Asterisk console. -----Original Message----- From: Noah Miller [mailto:noahisaacmiller@gmail.com] Sent: Friday, May 19, 2006 10:32 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] FAX over PRI Hi Tom -> I have had nothing but problems receiving faxes over PRIs with spandsp.

I only have one PRI at one of our offices, but we use it to receive faxes that are directly sent via Digium FXS to an analog fax machine. I've never formally tallied up the transmission errors, but we get something close to 100%. Maybe spandsp is an issue here. - Noah On 5/19/06, Tom Christensen <tomsmaillists@gmail.com> wrote:> I have had nothing but problems receiving faxes over PRIs with spandsp.

Spandsp or rather RXFax works on a few machines I hae quite well but on others it does not work at all, I have had good retruns with the HylaFax.IAXmodem combo on machines that could not use the RxFax. ________________________________ From: asterisk-users-bounces@lists.digium.com [mailto: asterisk-users-bounces@lists.digium.com <mailto:asterisk-users-bounces@lists.digium.com> ] On Behalf Of Tom Christensen Sent: Friday, May 19, 2006 12:18 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] FAX over PRI I have had nothing but problems receiving faxes over PRIs with spandsp. I currently have 4 systems, 4 PRIs from 4 different providers... none of them get better than 50% success rates receiving faxes in spandsp, I constantly get cut off pages. No body seems to have a fix for it, and it is really frustrating. Supposedly it is caused by "frame slips" on the PRI, but if that is the case, I am 4 for 4 getting crappy PRIs that can't keep time. These same boxes work fine when receiving faxes over fxo ports, or if I plug a fax machine into an fxs port and call in to a spandsp extension the fax will be received just fine, so I am left thinking it must be the PRIs, but if all PRIs are this bad, how can anybody be using them?

We also route via a PRI to our other phone system to hylafax on an analog modem and also to an analog fax. So what you want to do is fine and will work.

I just want to do Fax-To-Email using PRI channels as the incoming lines. Not so much transfer to a real fax. I am assuming that this is easily done with Asterisk? (I did it before with Asterisk SIP, but it only worked once every 10 tries or so) Mike -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Andrew Kohlsmith Sent: March 21, 2006 3:25 PM To: asterisk-users@lists.digium.com Subject: Re: [Asterisk-Users] FAX over PRI On Tuesday 21 March 2006 15:09, Michael Gaudette wrote:> How should I consider Fax over PRI channels with Asterisk? Is the > quality and reliability good, or should I be prepared for alot ofgrief? I'm having good success doing fax over PRI using a TE405; one span to the PRI, the other to an FXS channel bank that is almost obscenely underutilized (3 channels). I also have channel bank - T100P - IAX2 - TE405 - PRI, where the IAX2 link is a 1-hop SDSL (VOIP only) data link. This works well too. -A. _______________________________________________ --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 _______________________________________________ --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 The information contained in this email is intended for the personal and confidential use of the addressee only.
