Hello Juha,
The ENUM prefix for France +33 (3.3.e164.arpa) does not work, it is
delegated but the servers do not answer and the resolver times-out in
12-20 seconds. If you prefer to do ENUM look-ups before going to normal
PSTN this affect SIP call flows.
Do you have any idea how to work around this problem? Besides fixing
the DNS server side :)
Regards,
Adrian
