Steve,

  Sorry if my email was packed with TMI.  It was not meant to annoy anyone.  I 
just wanted it clear I am not analog stupid and had a solid reference for ATA 
performance expectations.

  I said "Started with compiling my own and [EMAIL PROTECTED]" and should have 
said "started with compiling my own with raw editing of .conf files THEN trying 
[EMAIL PROTECTED] as a packaged solution".

Thanks for your comments and suggestions.

Jim

Hi all, 

Sorry, kinda long but please read... 

I'm looking for some help or correction if I'm overlooking something. Let me 
preface this with I would be "the old guy on the block". I was installing 
channel banks from Rockwell when they were the size of a fridge for only 48 
circuits. Pre-Newbridge days when you had BIG cards for each circuit with dip 
switches not software. :-) 


Why the bibliography? I understand that you have been doing telephony for a 
long time. So have I, but just not as long as you, same understanding though. 




I've dealt with most big name PBXs, Centrex, etc through the years. I have a 
good data networking background and have a good grasp of common programming 
languages. I have evolved with the industry, now I'm into VoIP and loving every 
minute of it. I have been using Asterisk around 3 years. Started with compiling 
my own and [EMAIL PROTECTED] 


Most "Old School Telephony Guys" Hate VoIP. That may not be the case with you, 
but most people don't like change in general. 

Just for future reference, you don't really compile [EMAIL PROTECTED], it is 
just an image that you install. 




Here's my issue I hope to get feedback and help with; 

I have used many a SIP phone and by way of tweaking * and the phone's local 
dial plan I have been able to absolutely emulate the behavior and speed of dial 
out with any TDM system and their priority digital phones. Sound quality has 
also been matched if not better on the VoIP deployment verses the TDM 
deployment. 

However, this is NOT the case with analog phones. I have used analog FXS 
adapters from Linksys, Grandstream, Audiocodes and both Digium's analog cards 
in their TDM400 and the IAXy. 

Give Quintum a try, they are excellent. I have heard good things about Rhino 
and Xorcom. Do you know they stopped using 25 pair lines for stations, that 
could be part of the problem ;-P 





My issues have been proper passing of CID, support for hook flash in small 
caller id call waiting dependent systems, (home offices and churches), not to 
mention some installs requiring a bunch of tweaking to kill echo or volume 
issues. The hook flash support is faulty at times and full of clucks, clicks, 
slow returning dial tone. Basically a real feeling of cheap quality and 
"emulation" going on. 

In the past, on TDM systems, I used their ATA or a KSU or PBX analog port for 
any basic analog phone and it was both plug & play along with solid sound 
quality at all times. 

To be fair, it was not plug and play, you had to be somewhat skilled at the 
switch you were configuring and good with a 110/66 block and a punch too. Many 
times you needed a couple of people to bust out the toner to make sure you had 
the right pair. 



Heck I even placed modems or faxes behind them without issues, (yes, I 
understand why a modem or fax is an issue behind the VoIP to FXS conversion). 
Just throwing this out because it's another area where VoIP is behind the 
times. 


If I were you and I never will be, but I would try to adapt to the paradigm 
that VoIP is not behind the times, it is just trying to accommodate other 
technologies that are behind the times, such as modems and FAXs. 




Now don't get me wrong. I'm a major Asterisk evangelist and not pushing go back 
to TDM. My basis for crying for help here is we cannot forget the users of the 
world were trained and lived on TDM, both in business and at home. 
My mother can use a computer very well (and she was "trained" on a typewriter) 
and my niece is amazing with technnology for her age. 

Things get old and antiquated. Morse Code, VCRs, reel to reels, switchboards, 
betamax, even OTA non digitial TV in a few months. Everything changes, gets 
better, and people cling to the old ways. I know several people that swear that 
their old records and record player sound better than a digital CD. 




That's where their expectation is. What you sell better sound and work, in it's 
worst case, like the old TDM platforms did. 
And it does, at a MUCH cheaper price point, with many more features, if 
engineered and installed by someone who knows what they are doing. Flexibility 
is mind blowing. 




I should mention I have obtained the level and quality in an analog phone that 
is top notch without the emulation feel but it is only for the large users. 
That has been to do a Asterisk T1 connected to an Audit 600 using analog 
station cards. This paralleled the analog service delivery I could get from the 
TDM world, but it's an expensive deployment. 

I think you should try a few different vendors and solutions. What you mention 
above is going to give you pretty much the best analog. I am sure someone else 
can sell you something that does this with SIP. My personal recommendation is 
Quintum, but I am sure others do just as well. 





What have people used in a small deployment, 2 to 4 FXS ports, that REALLY 
performs like a traditional TDM delivered analog service? 


Generally, you buy a Digium or Sangoma board with the right number of FXO ports 
and then in install Polycom (or whatever) SIP phones. 

Personally, with both Digium and Sangoma FXS ports, I get perfect operation. 
Maybe try posting your configs instead of a book and biography. 

Have you explored your zap configs? There could be a simple setting that makes 
everything wonderful. [EMAIL PROTECTED] didn't really have much facility for 
that. 




Thanks for allowing me to rant, (fighting with a Linksys PAP2T on a home office 
Asterisk switch right now). 

Jim 



Thanks, 
Steve Totaro
