A service (SRV) resource record can be entered in a DNS to make IP-based services in a domain easier to find. Additional information on a service can also be made available (e.g. server on which the service is running, priorities, etc.)
Such a Service Resource Record can be created as follows:
_ctiserver Service Location (SRV) [1][0][7222] ucserver.domain.com.
| _ctiserver | Name of the service under which it can be found in the DNS. For estos ProCall this must be _ctiserver. |
| Service Location (SRV) | The type of record contained by these lines. |
| [1] | Priority of the service. This permits prioritisation of the different, similar entries. |
| [0] | Weighting of the entry. Is used to make a pre-selection of the DNS entry when the client setup is run. The following values are of particular significance: 0 - DNS entry exists but the static configuration is still pre-selected in the client setup 1 - 99 DNS entry is pre-selected in the client setup 100 - DNS entry is pre-selected; static configuration is not available. |
| [7222] | The port number under which the service provides the service is specified here. For estos ProCall, the default setting is normally client port 7222. |
| ucserver.domain.com | Computer which provides the service. Here estos ProCall expects the computer on which estos UCServer runs. |
How and where the Service Resource Records are created for specific DNS servers can be found in the corresponding manufacturer's documentation.
