Can FreeSWITCH generate the waivering tone?

IIUC, FreeSWITCH does not generate the dialtone. The VoIP phone will do that itself, and an ATA will generate it for a analog (POTS) phone. Your message wasn't clear if you are using VoIP phones, or an ATA (analog telephone adapter) with analog phones. A VoIP phone will "subscribe" with FreeSWITCH to a MWI login, and FreeSWITCH will send it a message whenever the number of messages waiting changes. In response, the VoIP phone will light the MWI and will play a stuttering dialtone when the handset is picked up.

According to http://www.voip-info.org/wiki/view/MWI "...most ATA's support stutter dial-tone."

Thank you Steve. I am not using an ATA. I am using opvxa1200+ e159:0001 OpenVox A800P. So, unfortunately, I do not believe the MWI stutter tone is done by the hardware (DAHDI/FreeTDM). I do not believe this card can send the MWI light signal as stated.

Yes, the stutter tone or MWI indication must be done by the hardware. When the user lifts the handset he receives dial tone from the card. That has nothing to do with FreeSWITCH. Now, there will be some sort of communication somewhere that lets the card know that it needs to send stutter tone or MWI down the line, but I'm not at all an expert on that. Fortunately we have someone who knows all about that stuff: Moy at Sangoma. :)

Moy, can you shed some light on how the MWI and/or stutter tone work with Dahdi and Sangoma cards?

Thanks,
MC

Thank you,
