I want to know if cisco IOS allows to manipulate with voice call disconnect cause codes. For example if the called number is busy, we will get "user busy" message as call disconnect reason. Can we manipulate it so that instead of User busy message, we could send ITU 34 i.e. "No circuits available" message to the originating end.
Many thanks for your reply. Can it be done by a TCL script?
Secondly what do these commands do?
Isdn voice-call failure
As far as I understand, they are only applicable to ISDN interface and not to H323 or SIP calls. Like if the call originates from h323 or sip and terminates on ISDN interface, then we cannot use these commands to manipulate what disconnect cause codes are sent to originating h323/sip gateway? Please confirm it.
Actually I am interested in sending disconnect cause code to the originating H323 gateway in a scenario as follows
originating H323 GW -> terminating H323 GW - ISDN inter -> PSTN -> User B
now if USerB is busy, PSTN will send back USer-Busy message to the ISDN interface, the terminating H323 gateway will then send it back to originating gateway over H323.
I want to know if I can manipulate the cause code that is sent to the originating H323 gateway i.e. instead of User-Busy , I should be able to modify it on terminating Cisco gateway and send whatever cause code I like.
Looks like it is not doable in cisco. Can it be done through a TCL scripts? Your thoughts please!
