[Asterisk-Users] Nortel Option 11

[Friend, George E.]

Question...I'm fairly new to Asterisk, but one location I'm looking at deploying Asterisk has an Option 11 in place already (it's actually in someone's HOME - long story).
 
Does anyone know if it's feasible to interconnect the two and use Asterisk to interface with the other offices and lines, and merely use the Option 11 as a gateway to use the existing digital handsets (Nortel)?
