we are facing a problem with FXO ports,We are using vic2-4FX0 with 2801 router (CCME).When we execute cisco IVR script (its-CISCO.188.8.131.52.tcl) for incoming call legs (for my company PSTN number) , its work fine. but when external user from PSTN disconnect its phone my internal phones or operator phone continuously rings. there is no automatic disconnection possible. only one way operator can disconnect his phone or stop ringing by manually pressing button on his phone set. Without execution of IVR script all things work fine no disconnection problem occur .
We have checked with both versions
i) Version 12.4(13r)T, RELEASE SOFTWARE (fc1)
ii) (C2801-IPVOICE-M), Version 12.3(14)T7
