>From widipedia, the format of a SRV record is:
_service._proto.name. TTL class SRV priority weight port target.
service: the symbolic name of the desired service.
proto: the transport protocol of the desired service; this is usually either TCP or UDP.
name: the domain name for which this record is valid, ending in a dot.
TTL: standard DNS time to live field.
class: standard DNS class field (this is always IN).
priority: the priority of the target host, lower value means more preferred.
weight: A relative weight for records with the same priority.
port: the TCP or UDP port on which the service is to be found.
target: the canonical hostname of the machine providing the service, ending in a dot.
Here is what the PDNS docs say:
SRV records can be used to encode the location and port of services on a domain name.
When encoding, the priority field is used to encode the priority. For example,
'_ldap._tcp.dc._msdcs.conaxis.ch SRV 0 100 389 mars.conaxis.ch' would be encoded with
0 in the priority field and '100 389 mars.conaxis.ch' in the content field.
So for you example, these are the fields stored in the DB:
name - _sipfedls._tcp
ttl - 3600
prio - 5
content - '0 5555 sip.me.com.' # without the quotes
Double-check results with dig.
