I'll reiterate too, it's a KOWN bug, that have been disused other times on
the list, but usually drop into silent, don't know if a Sofia-sip issue or
FS core issue (I don't have the needed knwoleadge over the FS code to state
that), but I could assure you it not limited to outbound-reg, it happens on
EVERY ONE AND SINGLE SIP request handled by FS where DNS are envolved,
TTL's are not honored AT ALL, doesn't matter if SRV or A record, once a DNS
result it's cached, it never expires.
