telephone cable to delay landline ring?
ProfTech:
Hello Ianobi,
Not disagreeing with you or arguing in any way but I've been playing with this on my 110. I thought I noticed that it was taking much longer to hear ring back on the PSTN after I upgraded to 2872. Started looking and quickly discovered that the "DetectOutboundConnectMethod" setting has been removed. I'm only dialing 7 digits so shouldn't be a long delay at all. Outbound route is [2-9]xxxxxx. I tried [2-9]xxxxxxS0 but it seemed to make zero difference. Currently set to default 500ms Dial Delay and on/off 100/100. Like I said, it just seems to be a lot slower. Haven't figured a way to time it exactly. ???

I'm not sure why "DetectOutboundConnectMethod" has been removed. It raises the question is it now set to one of the previously available options or to "none". I remain on software 1.3.0 (Build: 2824) and still have "DetectOutboundConnectMethod", although mine is set to "none". If your software is hard wired for the option "Assume connected after a short delay", then that will add a further short delay compared to the setting "none".
The "S0" setting only has an effect when applied in DigitMaps, not OutBoundCallRoutes. However, if your DigitMap is well crafted, then an exact match with [2-9]xxxxxx will be processed instantly with or without an "S0". If you have rule such as "xx." in the same DigitMap as [2-9]xxxxxx, then an extra two seconds will be added to the processing time unless you add the "S0".
Exact timings may be available via syslog. It's a while since I looked, but it might be interesting.
Timing by ear is very difficult as you are waiting to hear ringing tone from the called party and that may be influenced by all sorts of variables at their end.

ianobi,
I was suspecting the same thing. I'm pretty sure the "AssumeConnectedAfterAShortDelay" setting was the setting where the Obi generated its own "fake" ring to give the user the warm & fuzzies. I thought I read somewhere that the FCC mandated that a fake ring not be used. If that is the setting Obihai defaulted to and are leaving out the fake ring that could answer why the long delay. Just by ear it sounds greater than 4 seconds. maybe as much as 6. I mis-stated where I have the [2-9]xxxxxx. It is in the dial plan. I removed anything ending in xx. long ago. It is more of a minor annoyance than anything else. I've also noticed it takes a bit to hear ring when I dial a Callcentric number as well so not a big deal for me.

I wanted to update my original post. I did some more experimenting with Build 2872 and it seems that all of my outdials may have been delayed, not just the PSTN. I experimented with my Digit maps and I think I may have had an error that was causing an extra 2-3 second delay on dialing almost anything. Seems like it is working now. I sometimes hear ringback and sometimes do not but I think that may be normal.
