Hi all,
I have 3845 router added to CCM as H.323 gateway.
I am using this IOS : c3845-advipservicesk9-mz.124-3i.bin
and it contains 2 VIC2-4FXO cards.
I added the configuration :
caller-id enable
caller-id alerting ring " 2 and sometime 1"
I tried to change the cp tone and other parameters but no luck.
I used : debug vpm signal and I found:
get_fxo_caller_id:Caller ID receive failed. parseCallerIDString:no data.
but when if I connect analog phone to the line directly I can find the caller ID.
one more thing: When I can use the command:
caller-id alerting dsp-pre-allocate
sometimes I am able to find the dsp-pre-allocate and sometimes no?
