My company is looking to replace a malfunctioning Nortel BCM 200 that connects to a PSTN trunk (four incoming lines that share a single phone number). We have 13 i2002 and 2 i2004 phones that connect to the BCM (I understand that those phones will need to be replaced with SIP-compatible units).
I’m somewhat new to telephony, and we’re interested in replacing the old BCM with an Asterisk Switchvox SOHO system. We want to continue to use the PSTN lines, without going to VOIP. What information am I going to require in order to migrate over to Asterisk? Will we require a special card to connect the Switchvox device to the PSTN trunk line? I need to know if it is realistic to make this move before we decide to step into the abyss.
Thanks for your input and advice.
