RE: [Asterisk-Users] call to a particular 800 number never showsanswered on Zap channel
Is there a way I can tell if it is asterisk or the carrier that is timing out from the CLI? Sorry, I don't have PRI and don't know the details. However, I'm sure that if you set a high enough verbose or debug level, you'll see the ISDN messages between * and the carrier's switch. I don't know which terminology will be used, but you should see * send an IAM (perhaps called Initial Address Message or Setup) and the switch reply with ACM (perhaps Address Complete Message or Call Proceeding). Then, about 60 seconds later, you'll see REL (Release). Who sends it? If it's your carrier, ask them why it comes so soon. If it's *, perhaps your SIP phone is the culprit. If it's not obvious from its config, set up a local extension that doesn't time out to voice mail, call it from your SIP phone and see if it will ring for more than a minute. If neither your carrier nor your phone is timing out, then I guess it must be * but I don't know where that might be. Perhaps some * guru can help. Also, is there a way to force the phone to start the call counter or force the answer on the asterisk-side. I would guess that if you called Answer() before Dial(), then the call counter would start. However, it would also start on busy signals, rejected calls, etc. Sorry, I don't know if there is a way to have it start only when call progress is received. --Stewart ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

If I am really fast, I can navigate the menu system in enough time to be transferred to a real person, or at least the real-person queue and I get the answer supervision message. Is there a way I can tell if it is asterisk or the carrier that is timing out from the CLI? I thought if the timeout was not specified in the Dial statement it was unlimited, but perhaps I am looking in the wrong place. Also, is there a way to force the phone to start the call counter or force the answer on the asterisk-side.

I am still looking to solve this problem, does anyone have any ideas?
Thanks,

Thanks for the reply. Forgive me for being naïve, however have jumped in to
this asterisk project at work due to some circumstances beyond my control and I
don't know a lot about carriers and how this all works. I am figuring it out,
but it's a lot of trial by fire.
As far as I know, we only use 1 carrier for our system. We have a PRI from
NuVox and we use 7 channels for our asterisk server. So, I have a few
questions:
Is asterisk or the carrier causing the disconnect?
Is IBM (the 800 number I am dialing) not passing the answer supervision or is
that a function of the carrier?
Is there a way to make asterisk not drop the call or to force the answer on
this number? Seems like a hard-PBX would have to be able to handle this type
of situation.
Thanks,
Andy

This one drove me crazy for a while too. I found out that some
companies don't exactly play fair and don't pass answer supervision on a
call until you are actually speaking with a live person. The person I
spoke to about this wasn't sure if that was even legal, but he said it
happens quite a bit. I was lucky in that I use multiple carriers
(voipjet and broadvoice), voipjet disconnected the call after 60
seconds, but broadvoice did not, so when I find one of those 800 numbers
I route it through broadvoice.
Hope that helps,
