Graphs stats from the SNMP Host transmission MIB so should give a generic solution for ISDN calls In and Out. The MIB provides stats for all calls made and those that are connected. I've successfully used this MIB against Cisco 7206 Routers with mutiple PRI Lines and a 1603 with single BRI.
Uses a php script so the correct Interface Name etc can be collected from the IF MIB. Script based on those included within Cacti.
