>>Item 2:
>>The callIdentifier field is not currently optional in the IRQ. I see
>>these possibilities for callIdentifier in the case of a request for
>>information about all calls:
>>
>>1) state that if callReferenceValue is 0, this field is to be ignored
>>but filled with some data
>>
>>2) state that callIdentifier should be set to some dummy value, such as
>>all zeros
>>
>>3) change the ASN.1 definition so that callIdentifier is OPTIONAL, and
>>add appropriate text regarding its use in the field definition
>>
>>Since callIdentifier is defined as a SEQUENCE to allow possible future
>>expansion, I'd suggest option 1.
