Yes, I don't want to start a flame war and I am not really even advocating analog phones or a discussion of the relative merits of analog/sip. We are actually going the SIP route. My comment is more from the purspective of someone new to phone systems and what was important for me to learn. I initially thought we would lease a T1/PRI (which is what I normally think of as a "trunk" line, but obviously that is my limited experience with telephony single single POTS lines are also trunks), but because our call traffic is mostly internal we only need somewhere in the neiborhood of 6-12 phone lines to the PSTN. It took a while for me to realize that it was cheaper to buy a channel bank and a T1 card than to purchase multiple single fxo cards.
