While re-setting up my Asterisk system I decided that implementing call
routing through ENUM lookups would be a good idea. However, I've hit a
bit of a problem. Given DNS records like:
*.4.4 IN NAPTR blah
9.8.7.6.5.4.3.2.1.4.4 IN NAPTR blah
The first record is there to route all numbers starting +44 via a
particular gateway. The second record overrides that routing for a
specific number, which I want to route via a different gateway. The
problem is that it appears this stops a lookup for
"1.1.1.1.1.1.1.1.1.4.4"
from returning the wildcard record, which is a behaviour I hadn't realised
DNS had.
Is there a way around this, short of splitting up the override and the
wildcard domains into separate domains and doing the lookups separately?
It seems quite a short-coming of the ENUM system since I can imagine
telephone companies wanting to put a wild card in for their (large) blocks
of numbers but still having the ability to add more specific records (e.g.
for number portability, etc).
