I have 10 (ten) VB-44220 standard 22 button sets available. All in good condition, though they will need new desi's. I also have 1 (one) VB-43511A 8 trunk loop start card and 2 (two) VB-43611 8 circuit digital extension cards......in addition to the Panasonic equipment, I also have a Nortel 3x8 DR5 KSU, 2 ash M7100 sets, 1 black M7208 set, 1 black M7310 set, and 1 black M7324 set. All equipment is in great condition. The KSU, M7208, and M7310 could pass for new.....any takers?
