- Missing tag
- If any tag is missing, the original method (MakeCall parameter)
is checked. If the information is also missing here, it is not included
in the outgoing request. If the CLDN tag is missing, the MakeCall
instruction in the state table fails with an invalid number error.
- Invalid tag
- If a tag contains an invalid number, a notification error is returned.
The request continues with the erroneous tag removed. In the case
of CLDN containing an invalid number, the MakeCall instruction fails
with an invalid number error.
- Unrecognized tags
- Any tags names not recognized are reported and then discarded.
- Missing attributes
- If an attribute is missing from an otherwise valid tag, a value
is substituted from the SS7 defaults (see SS7 default values below
for details).
- Invalid attributes
- Invalid attributes are treated as if they were missing, so have
their values substituted with those from the SS7 defaults (see SS7 default values below
for details).
