similar to: spandsp <--> analogue modems?

I have googled until blie in the face, WiKi'd until physically exhausted and searched through every Asterisk repository that I can find, all to no avail... No matter which version of SpanDSP I use, with which version of libtiff, Asterisk, ... I simply cannot send faxes. I can receive faxes *perfectly* (sending from standard fax macine on POTS) into tiff file (via Digium analogue card),

I am having classic "frame slip" symptoms on 4 different systems with 4 different providers (all full PRIs, Qwest, XO, Xspedius, and First Digital are the providers). By classic I mean pages cut short. I do not hear clicks on calls however, and faxing from a fax machine plugged into the asterisk box via an fxs port (no VoIP) faxes just fine through the PRI. Also, faxing directly from

> Actually.. I seem to have jumped to improper conclusion.. One thing you will find abour spandsp is that some fax machines will just plain have a problem sending to spandsp, period. Mr. Underwood has localized it to cetain HP fax machines and I can confirm that HP all-in-one SOHO machines exhibit this problem, but I have also noted it with Canons and Panasonics. In my context, I have several

Hi, I'm using app_pppd with a Digium-PRI-card for PPP connections. I had some strange problems with some IP packets passing and some not, e.g. ftp login went well, but as soon as I tried to up- or download a file, noting was transferred. I finally guessed, it must have to do something with the packet size. Then I started pppd with the parameters mtu 296 and mru 296 as in further times with

Does any one knows of an Windows based SIP video phone???...

Hi, People often send me audio logs from spandsp's soft-fax machine, where they have problems with corruption in the middle of a page for most or all of their faxes. Their problems are usually due to frame slips. However, recently I have received audio logs from two people who generally have great success with my software, but who find one or two machine regularly fail to send faxes

This really only seems practical in a corporate environment however, I would suggest decoupling the creation of faxable material from the act of transmitting it. First use CUPS/Samba to create a 'print to PDF' printer (http://www.google.ca/search?q=samba+pdf+printer) Second use an LDAP to look up to return the email address of the submitter of the job and send them the resulting PDF

I've seen people mention that they have fax reception working with Asterisk, spandsp, and app_rxfax. I'm using the latest Asterisk from CVS, SpanDSP 0.0.1k, and the latest app_rxfax.c (as mirrored by friendly list members recently), and libtiff 3.5.7. Asterisk is detecting the fax signal properly, and executing the fax extension in the dialplan. The fax part of the dialplan is pretty

I've seen there are spandsp, iaxmodem to simulate a modem for receiving faxes under asterisk. Hylafax can be "tricked" to think it is a real modem. Can I create a dialup/access server with the same method? Can ppp run on top of this "software" modem?

Hi, I'm looking for a mean to send digital data over an E1 line, just like isdn4linux or Capi via AVM's FritzCard is able to do it with BRI lines (e.g. for PPP or ISDN raw connections). I'm not looking for modulated audio data representing digital data, like fax or the analogue modems of former times. I want an interface to the ISDN raw data, with an outgoing call marked as

Hi all, I am interested in interfacing a GSM modem to *. I've seen a few comments about doing this, but I'm not clear whether people have actually made it work. I've used GSM modems for various data jobs, mostly high volume SMS (no, not nasty marketing stuff - high volume solicited SMS :-) ) . These only have analogue ports for voice. Does anyone know of units with digital voice

I've just had to replace my Hylafax server as the cooling fan in the rack case has died and could not be replaced. My box runs three fax modems, one for each of the original 3 fax machines that got skipped years ago. This means that I now have 3 lots of: USB to seral converter (new box doesn't have any COM ports. 9pin->25-pin serial cable Modem power supply phone line analogue port

+1 spending money to get that many fxs ports is going to negate any savings of reusing analog phones instead of buying ip phones 1000 analog ports sounds like hell and if it was me I would be embarrassed to have a setup like that tied to my name if I was a consultant etc. Someone will come in after you and ask who set it up and the customer will say you :) On Feb 17, 2016 4:23 AM, "A J

So made my first forray into 1.4 and DAHDI and hit a problem. (Not convinced this is a DAHDI issue though...) Testing an analogue line and asterisk sees the caller ID being passed, but then fails to detect ringing. A plain old analogue phone plugged in rings just fine. Console output: == Starting post polarity CID detection on channel 4 -- Starting simple switch on

Hello; I am facing a trouble with A2Billing when using analogue lines because the channels are not closing properly when dialing happen through A2Billing (it seems the dialing scenario including the hangup is not handled properly through A2Billing but I do not have control on this). But when I do dialing from asterisk and using analogue lines, I do not face a trouble because I can write the

I have a potential customer who has an existing PBX with analogue FXS ports connected to phones. He wants to allow a single remote worker to be connected to one of the analogue extension ports using VOIP. I know I could do it using Asterisk with an X100P card, but that seems a bit overkill. Does anyone know of an analogue->VOIP adapter that has an FXO port in it instead of just an FXS port?

Hello ! I 'm trying T.38 faxig with spandsp using rxfax/txfax as fax terminal. As another endpoint I 'm using Grandstream HT 486 ATA and a fax machine. Has anybody success with the HT486 as T.38 terminal ? ATA as originator: I managed only onetimes a successfull T.38 fax session. The other times the HT486 did not initiate a re-invite with T.38 parameters. Or shall the Terminator

Hi Everyone, I want to fine tune the Rx and Tx gain on an analogue Sangoma card by dialing into another server that is running on Sangoma PRI card (both services on Bell network). [mwatt1004khz] exten => s,1,Answer exten => s,n,PlayTones(1004/1000) exten => s,n,Wait(300) If I match the Rx/Tx numbers on both sides by monitoring "ztmonitor X -vv" am I right with my theory of
