When Fax Modem Dials It is Causing a Fast Busy

(1/4) > >>

audioresearch:
When I my fax modem, which is connected to the "phone" port on my obi110 dials a number, after a few dtmf tones have been output, a fast busy suddenly appears and the call cannot get through.

I have no problem whatever dialing the same number using a phone handset and doing the dialing manually by hitting the dtmf dialing buttons-call goes through every time that way.

I'm guessing that the fast dialing speed of my fax modem is being rejected by my obi110. I have limited control of my fax modem. I'm running Windows XP and I did change the init string sent to my fax modem to change the values in modem register s11. I tried the max and min allowed values in that register. It had no effect, when my fax modem dialed out, the fast busy signals always appeared after only a few dtmf tones had been dialed.

Also, before I got my obi110 (which is being used with Google Voice), I used this same fax modem on my Comcast telephone line and it always dialed out without a problem.

It appears that my fax modem and the obi110 do not like each other.

Any ideas how I can fix this?

I am able to login to my obi110 using my web browser pointed to its ip address and I then get the "expert" obi configuration screens, so if you have any suggestions for changing anything there, I can probably do it easily and then try it out.

Thank you very much for any help you can give.

I assume you are using a software to send a fax. By including a "," in the dialed number usually inserts a pause.

I would put a splitter where the line cord goes into the Obi and connect the fax direct to the line.

lhm.:
Try this free Fax software from USRobotics for Windows OS (works on about 900 different modems) http://www.usr.com/bvrp/bvrp.asp?loc=unkg

Works for me.

Thanks for tip about using comma for pauses. I knew there was something that did that, but it's been so long since I used I had forgotten what the character was. Unfortunately though, putting in zillions of pauses with commas did not help the problem.

I also got my obi to use the current Verizon phone line I have connected to the OBI fxo port for outgoing calls, but that also did not help-when my fax modem dialed only a few tones, the fast busies still happened.

The Obi call log never shows any calls made or attempted when my fax modem quickly causes a fast busy.

Looks like I will have to temporarily connect my fax modem directly to the Verizon line every time I want to send or receive faxes.

Thanks also for the tip about using the value {@|?:} in the incoming call routing field for the line port-that did stop any calls coming in over my Verizon phone line from ringing my phones.

Possibly, the Obi has problems with devices such as fax modems that dial fast-if so, maybe the developers could come up with a fix???
