In short:
1. RasSrv::RewriteE164
2. Authentication (may also perform rewrite or route the call
to a specific alias or IP address, as in case of RADIUS, for example).
3. Check if the ARQ (or Setup) message specifies destination
IP address explicitly - if so, use it and go to the point 8.
4. Check if the first destination alias matches a virtual queue.
Issue a RouteRequest command and wait for RTA, after RTA
go to the point 1 again.
5. Try to find a destination endpoint by an alias or a prefix.
If found, go to the point 8.
6. If ParseEmailAliases is turned on, try to check if any alias
is in a name@dns form. If a match is found, go to the point 8.
7. If the call is from a parent gatekeeper, perform reverse
[Endpoint::RewriteE164]
rewrite and try to find an endpoint by an alias or a prefix.
8. If no match is found so far, send ARQ to a parent gatekeeper
(if it exists) and go to the point 10.
9. If no match is found so far, send LRQ to gatekeeper neighbors
and go to the point 10.
10. That's all.
For unregistered calls (no ARQ, only Setup received), the sequencse
is similar, except that no parent and neighbor gatekeepers are queried.
Also, virtual queues are not used in this case.
