recently we are working on this scenario to send and receive faxes. the offramp portion does not work at all but the onramp section works with problems. the problem is that sometime just the portion of the pages that we send via fax machine are received by mail accounts (for example half a a page). my configs are as follows:
c2921(config-dial-peer)#do sh run dial-peer voice 33 pots service onramp-app incoming called-number ... direct-inward-dial port 0/0/0:15 dial-peer voice 99 mmoip service fax_on_vfc_onramp_app out-bound max-conn 48 destination-pattern 866 information-type fax session target mailto:firstname.lastname@example.org dial-peer voice 29 mmoip service offramp-app information-type fax incoming called-number 8.. image encoding MH image resolution fine dsn delayed dsn success dsn failure dial-peer voice 54 pots max-conn 48 destination-pattern 8.. direct-inward-dial port 0/0/0:15 forward-digits all dial-peer voice 98 mmoip service fax_on_vfc_onramp_app out-bound max-conn 48 destination-pattern 868 information-type fax session target mailto:email@example.com ! ! ip domain name test.fax ! fax receive called-subscriber $d$ fax send transmitting-subscriber $s$ fax interface-type fax-mail mta send server 10.1.1.101 port 25 mta send subject "mail from fax" mta send origin-prefix "cisco-powerred Fax System" mta send postmaster firstname.lastname@example.org mta send mail-from hostname router.test.fax mta send mail-from username $s$ mta send return-receipt-to username $s$ mta receive aliases test.fax mta receive maximum-recipients 48 mta receive generate permanent-error ! application service offramp flash:app_faxmail_offramp.126.96.36.199.tcl ! service fax_detect flash:app_fax_detect.188.8.131.52.tcl ! service onramp-app flash:app_faxmail_onramp.184.108.40.206.tcl !
in the above configuration, I've created two dial-peer for to internal fax numbers (866 and 868) so if fax is sent to 866, the mail is sent to "faxinbox2" mail account and the fax is sent to 868 is delivered to "faxinbox1" mail account. sometime the pages are delivered completely and correctly to mailboxes, but sometime just the half of the pages are faxed. I've tried this on many fax machines. any help would be appreciated. tnx.
I tried to configure T37 onramp/offramp fax in my network but after several attempts I failed to apply it completely and just portion of that worked well. despite describing the scenario in many forums (like here), I got nothing!
anyway, I'm going to test it in a simple form. I mean, I want to connect my edge router to PSTN line via an FXO port and via ethernet to internal network. my internal network has many physical fax machines that have gotten their internal tel numbers (like 866, 867, ...) from PBX . so can I use this scenario to configure the router to support these fax machine, or I should connect fax machines directly to router through FXS ports? tnx.
