Hi, I have read a lot about the thread of faxing support in Asterisk as well as spanDSP. However, either I don't fully understand other people's applications or may be what I'm trying to do is different from what others are trying to do. I have a very simple setup. I have an asterisk server with a TE110P connected to the PSTN via T1 PRI (Asterisk A). I have another asterisk server with a TDM40B board with 4 FXS ports (Asterisk B) where I have an actual physical fax machine connected to one of these ports. These two machines are in two separate locations connected via a point-to-point T1 circuit. What I wish to do is program a DID on the T1 so that when the call comes into Asterisk A on that DID, it will be routed via IAX2 to Asterisk B, which will in turn patch the call through the FXS port where the fax is connected. Obviously, I also wish to be able to send faxes in a similar opposite direction. Is this possible with Asterisk? Will it work? Thanks, Waldo

And totally unrelated to spanDSP and other discussions related to turning Asterisk into a fax machine. Apart from the relatively trivial task of configuring your two Asterisk boxes to route calls appropriately, the only two things you need to pay attention to are (a) ensuring you use g711 for the IAX2 link (using, or permitting, any other codecs will destroy the integrity of the channel as far as data/fax modulation is concerned), and (b) ensuring that your IAX2 traffic takes priority on the T1 circuit so that other large data transfers do not introduce so much jitter or packet loss as to render the VoIP traffic unusable. -- George Pajari, netVOICE communications 604 484 VOIP (484 8647 x102) Open Source VoIP/Telephony Specialists 1 877 NET VOIP (638 8647 x102) www.netvoice.ca www.ip-centrex.ca www.digium.ca www.grandstream.ca www.sipura.ca www.snom.ca

Will it work?The bottom line is that it may work "if" you run g711 across all machines; including the iax link. g711 is the only common codec that would come close to supporting modem/fax calls. Personally, I'd give that about a 50% chance of working.

We use fax over IAX with 98% success rate.
Hi, I plan on setting up an asterisk server to be used as an email-2-fax/fax-2-email server, for a company that sends and receives faxes almost 24/7 (milions of fax pages every month).>From your experience in this, can Asterisk handle the heavy load? Iintend to purchase a Saphir V PRI ISDN Adaptor for them. Thanks, Alex.

Hi, I wonder, how reliable is spandsp for faxing with asterisk as an endpoint when using digital pstn lines (Sangoma AFT-board)?

Is there a way to use a regular (analog) fax machine with Asterisk? I suppose it coule be achieved by using some ATA device, but is it possible without that? Cheers, Vedran. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20051126/cf160355/attachment.htm

Hi, How can we change the FROM address when Asterisk sends mail. For example it is sending asterisk@asterisk1.local in FROM , I need to change to abc@abc.com. Any help? Thanks Wazb
My experience has been that this change will update the from address of the email notify, but the "pager" notify will still come from the user running asterisk. Unless there has been a change since 8/2005. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Aaron Daniel Sent: Thursday, April 20, 2006 12:00 PM To: wasif@thecommstore.com; Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Asterisk FAX Open voicemail.conf Find serveremail=asterisk If it's commented, uncomment it Change it to the email address you want it to be.

Hi, I have configured Asterisk with Fax-to-Email feature. Fax is coming to Asterisk through DID. What is happening is that sometimes Asterisk receives Fax in first attempt and sometimes in 2 to 4 attempts. On DID Sip,G711 codec & T.38 protocol is enabled. Please advise me how I can make Fax service more reliable on Asterisk. Thanks Wazb
