Howdy I have a question regarding support for picking up when the telco sends a MWI message. My client's setup is a small office with three incoming lines on a TDM400P with iaxy's and a Grandstream as extensions. I am using CVS Head from yesterday. (I was resolving a different issue.) Since they only have two voice lines, with the third as a fax, I am using voicemail from the telco. What I am seeing is an event every half hour exactly, on each of the two voice lines. This causes the simple switch to kick in and ring the extensions. Of course there is no one there. I have put a workaround in the dialplan of using WaitForRing(0) as the first entry in the s extension. The downside is that it delays the ringing of the extensions by one ring which my clients don't really like. Since these events happen every half hour and only on the lines that have voicemail I am very confident that it is the telco sending a trigger to turn the MWI on the phones either on or off. I really don't want to have to try and find out from the telco as their support is much, much, much, less than knowledgeable or helpful. What I am wondering is if there is any way for Asterisk to pick up on these message from the telco. It would be great to set the MWI on the extensions and remove the delay in ringing. I have searched through the Wiki and lists.digium.com to try and track down information to no avail. I think I have looked at every message that has "MWI", "stutter" or "message waiting" in it. Everything that I can find only relates to Asterisk's voicemail. Any ideas or pointers are appreciated. Cheers Scott Petersen Xavier Solutions Inc. 250-216-5407

You can also free that third line up for voice if you use faxdetect. -Seth -- Seth Remington SaberLogic, LLC 661-B Weber Drive Wadsworth, Ohio 44281 Phone: (330)335-6442 Fax: (330)336-8559

What I amI found that when I'm dealing with a technical issue on POTS, I get the best results by personally visiting my CO and hoping a nice person answers when I ring the bell. For example, I finally got my DSL to work through this approach: it was up and down often, apparently related to ambient outdoor temperature. I got to know the (then US west, now qwest) DSL tech who handled that CO and worked with him directly to resolve the issue. When he could see that he'd need to spend more than just a few minutes on a job, he'd take my phone number and tell me to call the 800-number service people. When they generated the work request and he received it, he'd call me directly to find out what the real problem is and get it addressed. So what I'm getting at is that you might find it advantageous to at least try talking with techs in your particular CO. They're much more likely to understand what you're asking about and to know the answer than a 800-number support rep. Just make sure you're nice and avoid taking more than just a few minutes of their time. Greg
