similar to: Modem support via Cisco FXS ports?

Hi all, forgive the question but is it possible to use PCI modem cards (aka winmodem's) as FXO/FXS ports in * ? what about external modems like the USR Sportsters? Thanks in advance, Bryan. Bryan Nolen Lead Developer http://Arc.Net.AU http://cdonline.com.au

I have a couple of devices that need an analog modem to communicate outside of our Asterisk system. Most FXS gateways don't seem to support this... I have a stack of Sipura 2002's that are, AFAIK, worthless for this purpose. I've heard that Digium's IAXy FXS will work with modems, but I can't find any reference to that in their documentation. There is also the

In the past we have used Adtran Atlas 550's to break out FXS ports for devices like modems. The great thing about the 550 is that internally it is all TDM so there is absolutely zero latency. We are able to use ATA's for faxes and analog phones but devices that use modems, they fail 99.99% of the time when using an ATA. We tried to migrate to TA908 devices; they have FXS ports built

Hi, all Can a normal PCI modem be used to provide PSTN interface? I have seen modems that have answering machine capabilities, so there should not be a problem sending voice through them. Certainly, modem will be cheaper option then dedicated cards.

Hi all, I like to have a dial in modem on my toll free number so that when I or my employees travel, they can always get in for net access to read email if no better method is available. Right now, my Panasonic KX-TD1232D PBX receives the call on a POTS line and routes it to an analog modem. The speeds achieved are around 24 kbps due to the digitization of the KX-TD1232D introducing

Hi guys, I think I posted on this issue before, but didn't get a response. I've still not been able to resolve the issue. I've got a small installation of Asterisk running one 4 port FXS Digium card and 1 FXO Digium card. I'm having difficulty routing modem call through one of the extensions out through the FXO card. By difficulty, I mean it won't work. The calls

Happy New Year, I have a project to pass modem calls through * convert them from IP to X.25 and then allow the modems at each end to talk thru the rtp stream to each other before calling modem terminates the call. Datamodem --- FXS(non *) ---- ADSL --- * -----Software Application ---- X.25 ---- modem While the above occurs I also wish to capture the data stream and also parse selective parts

Hi everybody. I know maybe this question has been posted some time ago, but I need your updated opinion on the subject. I'm replacing our old pbx with asterisk. I have two TE207 dual pri (e1) cards on a clustered system (one on each node). I absolutely need to connect 4/5 analog extensions with modems, they're being used for remote assistance on very old systems which cannot be upgraded

I have an intermittent problem with the one FXS line that I have. On most calls, the first ~5 seconds of the call has a loud buzzing noise on the line. After 5 seconds or so, it fades off to nothing, and the sound quality is great. Searching for "buzzing" on the list doesn't give a whole lot to work with. The buzzing happens on calls that are routed over both my FXO line and

Hello list. I've been running a Cisco VOIP WAN for the last two years using CallManager V3.2. The remote 1760 routers are set up as H323 gateways. I've got a VG200 that is my PSTN gateway with a full T1 voice trunk to the local CO. I'm also running Unity v3.x for voicemail. We are currently using two ATA186 devices that are using the G.711 codec to pass incoming calls on the T1

The problem with using Voice Modems is that they fall into two categories: 1) Hardware Modems which only have half-duplex transmission of voice 2) Soft/Win/Lin modems which are proprietry and don't have asterisk drivers Please shoot down this recipe before I waste any time trying to acheive it: Rationalisation: ---------------- In Australia and I assume other places, there is no

Hello, I am currently trying to configure an Asterisk (current 1.4) box with a TDM410P and 2 FXS as well as 2FXO modules. An analog modem is directly connected to the TDM (port 4) which itself is directly connected to the PSTN (port 1). [V.34 Modem]-----[TDM on Ast. 1.4 TDM]---PSTN When I try to establish an analog modem connection with this setup, the modem is unable to connect to the remote

Hi, I wish to know if GNUGk can work with * running as a gateway with the Digium FXO card. Kindly share your experiences in case there are some issues which one must know before going in for such a setup. Also, I've been reading about the DialTone detection capability by the hardware in different countries. What are the issues with it? Thanks & Regards, Deepak ----- Original Message

I'm having major problems routing a modem (data) call through my Asterisk box. I've got a single incoming POTS line through my X100P, and a few extensions (and modems) plugged into the ports on my TDM400P. I've been using the system for a few weeks for voice applications and everything is working pretty well in that area. But just recently I was trying to place a data call on

Hi guys! I bought an device that it is used to connect two PBX, two modems or two phones. It has two RJ11 connections. If you plug two phones and pickup one the other one will ring. I am trying to use this device as a FXS to FXO converter with a X100P Clone. I plugged one end at the modem and the other one with a phone. The problem is that when I load the wcfxo module this device thinks

My office is investigating using an Asterisk PBX and also going to a VOIP provider for our main phone connections, but one of the tricky things is that we need to have outbound and inbound modem calls (fax too). I see a lot of talk about faxes but no mention of modems on this list. I get the impression that modems will be a problem for us. Is that true?

I am playing with a USR (us robotics) USB modem model 5637. in the past I used internal modems and had no issues. One this unit I plugged it in, dmesg says its recogized. I did "ln -s /dev/ttyACM0 /dev/ttyS4" this works. I then did "cu -l /dev/ttyS4" type "AT" and I get OK... looking good. When I "ATDT my number" I get a connection at 1200 baud (which I

Hello everybody I am trying to connect my asterisk to a payment equipment trough PSTN. I have a TDM400P card with an fxs module an the equipment use modem to send data! I was thinking to implement a software data modem in asterisk, but I found out that there is just faxmodem for asterisk, Is anyone here know something about software data modem working with asterisk to help out? Thanks,
