[Asterisk-Users] FX-200 VOIP PORT CONVERTER FXS to FXO

[Ed Rubright]

Hi John,

Thanks for the info.  I'll be stopping by Radio Shack to pickup a
polairy tester.  I have 2 X100P and 1 TDM400 card.  I will be adding a
SIP phone here in the next week or so.

What do you recommend for the following:

- What echo cancellation settings in the zaptel makefile? 
- What echo settings in the zapata.conf for the X100P interfaces?
- What echo settings in the zapata.conf for the TDM400 interfaces?

Thanks in advance for you assistance!

Ed

In the old days, phone plugs looked like 1/4 phono jacks
There was the TIP of the jack and the RING at the base 
of the jack.  Hence  TIP and RING

The easiest way is to go spend $10 at your local radio shack and buy a
polarity tester.

TIP/RING issues also used to cause speed problems with Pre V.90 modems.
Most modern modems today have auto polarity sense / fix hardware built
in..
