Ohhhhhhhhhhhhh,... Sorry. I meant to imply that once the application dials a phone number, has a delay (so it can dial extensions) it plays a wav file to the mailbox it dials. So it simply calls an IVR here at the office and leaves someone a voice mail. The wav played is not DTMF but a voice that we choose.

PS, I gave 'good answer' :)

Hey Luc If you can clarify one thing, so if I have a modem that is TAPI compatible, it may still not be considered a 'voice' modem. In the sense that it can not play a wav file after dialing a phone number. The modem modem I currently have is the USR 5637 but I am now permitted to get any voice modem avoiable?

Did you ever resolve this? What modem type are you using?

Ever resolve this? I'm in the midst of applying working proofed wav functions but lacking a good choice for a good modem.

Reply to my own message is what I want. I want to find the best voice modem out there (but it is ok to have some short comings as it seems there is no clear winner). What are your thoughts as per voice modems? I'm not concerned over flash-hangups (line switch) but mainly want to be able to send wav's to a modem to play after dialing and navigating through an IVR. So I can conquer the initial menu navigation with delays in the ATD command but after that simply need to leave a message (internal alert type system from server). any recommendations on the optimal voice modem?

Must be something with the audio..... I chopped up the wav into portions. The first portion was skip free, so i repeated that over and over and no skips, then i played a portion that skipped and it skipped so it must be the wav file. though i believe i had re-encoded it properly. will investigate. But a bigger issue, have you been able to send key tones? I want my system to dial extensions but from some early readings i may have to gimck this. the other issue is i am targeting a USR5637 56K USB Faxmodem. but it appears that the only at command that gives me an ok is 'at' and 'atd'...... hey, can i give you my email? dotnetcoder@hotmail.ca

So I have made some EXCELLENT progress. Practically done. What is left is finessing the audio into place. Right now. I take a wav file, and break it into blocks as per some examples. But when I listen to it over the phone it plays for the first couple seconds, then it starts to sound like it's skipping. PS:I will help anyone who reads this. Email me @ dotnetcoder@hotmail.ca. But if I can get help here is my audio loop. BinaryReader rdr = new BinaryReader(strm); Utils.Write("4"); while (!MSwitch) { byte[] bt = new byte[1024]; bt = rdr.ReadBytes(1024); if (bt.Length == 0) { MSwitch = true; break; } comPort.Write(bt, 0, bt.Length); } Before this, I read the stream after the 44th byte. Starts fine, but I think the program is writing too fast?

Hey all, Anyone have a very simplified/bare-bone cookbook sample to play a wav file over a serial port that was dialled? So far I have successfully made a c# app that opens port, dials phone number and the app sleeps for a few seconds till i pick-up phone, i received the phone but then am now at the point where my code should play a wav file. Anyone have a sample? Tia charles

Circle gets a square! It was all about timing. Thank you!

I have an app that replies to all AT commands except for ATD7059999999. When I go to HyperTerminal all commands including ATD7059999999 works. I even tried ATDT. What can Hyperterminal be doing that I'm not?

I'd like to create a project that will work like a humerous alarm system in an office. Not overly because I don't want it to wear out but not lame either. My idea surrounds a monitor that runs on a linux box (ubunto). I want to attach a switch that when the monitor detects failures of any sorts we'd get a light and maybe some sounds as to catch attention (but fashinably). Currently the monitor exists on a server that has frequently update information to present in graphs, thru a browser (fire fox). But I am not limited to creating an entire mini application (hopefully) that sets off some hardware attached switch that turns on some neat humerous system. Any idea? or examples? Links? Tia Charles

lolololol. thats too good

Weeeell i hope i don't become addicted then. I just started reading.... ekkk!
