Hello CSC
Problem Description
- I have a C2811 GW with c2800nm-adventerprisek9-mz.151-4.M12a.bin and one VIC2-4FXO connected to a legacy 4xSIMs GSM GW for outbound calls to cel numbers. Each GSM GW FXS port is a SIM card, and each one is connected to a VIC2 FXO port
- To avoid future user complains when one SIM card is blocked by provider, I’m trying to setup a trunkgroup/dial-peer path selection config to automatically change outbound call to other SIM when this happens.
- However, when one SIM card fail, the FXO port is always up and there is no way to distinguish between a OK/Blocked SIM from 2811 FXO port up/down state to make desired path selection working. To make trunkgroup/dial-peer path selection work, I have to either manually shutdown the FXO port with Blocked SIM, or set it in busy forced mode
- I captured the error tone (attach audio) from a CUCM ext when call is routed to a blocked SIM FXO port and configured the corresponding custom cptone for disconnect, but 2811 still not detect error to pass to other FXO-SIM working:

I don’t know if I can do anything else from FXO ports/tones config, or should I look other options like i.e: make an EEM script to constantly test FXO ports and shut/busyforced when SIM is blocked according to htsp_process_event above (if its possible)
Thanks in advance
Regards
