-- Attempting call on DAHDI/1wwwwww for smvoice_callprogress at smvoice-dialout:1 (Retry 1) [Oct 16 14:36:42] WARNING[16408]: chan_dahdi.c:8132 dahdi_request: Unknown option 'w' in '1wwwwww' [Oct 16 14:36:43] WARNING[16408]: chan_dahdi.c:1481 dahdi_enable_ec: Unable to enable echo cancellation on channel 1 (No such device) Does DAHDI not know about the W ??? I think zaptel used to. I am trying to come off hook on port 1 of my card and wait 3 seconds before my AGI runs. Is there something new for DAHDI instead of "w"? Jerry

Dumb modems have been able to detect dial tone before dialing for many a year, but the "w" cludge seems the only way to CYA when a PSTN switch is slow to return dial tone. This shortcoming has been built in ( or not ) for many a year, and no one who has the skills ( I certainly don't ) is interested enough to correct it. Analog PSTN interfaces will be around for a long time. It deserves some attention. John Novack -- Dog is my co-pilot

It should be DAHDI/1/wwwww This does work. I wanted to share back. Thank you. jerry
