2. where & what we need to chcek? any hardware or IOS issue?

3. main and important thing whether during such error logs there is load on MGW and due to over cpu utlization call which attempt on MGW may failed? if yesy its failed with MGW end or failed from source end as abondan? or else if MGW disconnect then what is ISDN casue code.
