cessed at least from the snom.com host (currently at IP address
217.115.141.99).
• Please tell us the login address (host and port), user name and
password. We need root permissions on that host.
• Please tell us for which domains you plan to use the server. Please
also tell us where you want to process the requests (which outbound
proxy to use for NAT Filter).
• Please don't run too many other services on the host that can de-
grade the performance of the server. We recommend using the serv-

https). We recommend not using the standards ports, as they some-
times trigger inappropriate actions on immature equipment.
• Please set your DNS SRV records for SIP up so that they point to the
NAT Filter SIP UDP port. Please don't use other transport layers than
UDP. Do not set up DNS SRV records for TCP or TLS.
