We’ve been having trouble with our integration of an Asterisk server and our old Sasmung Prostart DCS.  The two are connected via FXO ports on the Asterisk-side, connected to SLI cards on the Samsung-side.  The problem involves background noise on the lines, lines not hanging up when they’re supposed to, and lines randomly diconnecting during a call.  I’ve traced some of the issues to bad cables, and more to bad ports on the Samsung-side.  Then yesterday I was doing some more reading about the specifications of our Samsung hardware and found something interesting.  When providing analog circuits throug the Samsung Proaster DCS there are two interface cards available, the SLI and the SLI-8.  The SLI provides four analog port while the SLI-8 provides eight.  Up until yesterday I thought that was the only difference between the two.  While reading through some technical manuals I had, I discovered that the SLI is equipped with a DTMF receiver and provides overvoltage protection, while the SLI-8 doesn’t.  So guess what.  All of our analog ports are provided via SLI-8 cards.  We always assumed we wanted the most bang for our buck, so eight ports instead of four seemed to be the wiser investment.  Now it seems we may be losing some key features for the integration we are attempting to work because we’re using the SLI-8 cards instead of SLI cards.

So yesterday i ordered a couple of SLI cards and will install them next week sometime.  Lord willing, this will fix the issues we’ve been having.

In other news, I paid $1.59/gal. on gas yesterday!!!
