[cisco-voip] testing new ACLs: VG224 issues (RESOLVED)

[Lelio Fulgenzi]

The problem arose after testing with a VG224 analog line as the calling party, however, the problem manifested itself with any device as the calling party. So, in essence, the problem has nothing to do with the VG224. 

The VG248 comes into the picture because it triggers the problem. If the called party has a shared line on a VG248 and that line's max/busy setting is set to 2/2, the called IP phone will drop the first call when it tries to answer a second incoming call.

So you were seeing this when you had a line as a shared appearance on 
a VG224 port and a VG248 port? Where did the 248's come into the 
picture?
