To add SRV records, follow these steps:

  1. Sign in to your DNS host’s website.
  2. Choose your domain.
  3. Find the page where you can edit DNS records for your domain.
  4. In the boxes for each new record, type or copy and paste the following values. (See the notes below for creating SRV records when your DNS host does not have all of these as separate fields.)
  5. When you have finished, save the records.
Note: Typically, it takes about 15 minutes for DNS changes to take effect. However, it can occasionally take longer for a change you've made to update across the Internet's DNS system.

Notes:

  • For Name: If your DNS host does not allow setting this to @, leave it blank. Use this approach only when your DNS host has separate fields for the Service and Protocol values. Otherwise, see the Service and Protocol notes below.
  • For Service and Protocol: If your DNS host does not provide these fields for SRV records, you must specify the Service and Protocol values as the record’s Name value. (Note: Depending on your DNS host, the Name field might be called something else, like Host, Hostname, or Subdomain.) To set up the combined value, you create a single string, separating the values with a dot.
    • For example: Name: _sip._tls
  • For Priority, Weight, and Port: If your DNS host does not provide these fields for SRV records, you must specify them as the record’s Target value. (Note: Depending on your DNS host, the Target field might be called something else, like Content, IP Address, or Target Host.) To set up the combined value, you create a single string, separating the values with spaces and ending with a dot. The values must be included in this order: Priority, Weight, Port, Target.
    • For example: Target: 100 1 443 sipdir.online.lync.com.
  • Variation for Priority, Weight, and Port: Some DNS hosts provide some, but not all, of the required fields separately. For these DNS host sites, specify the values that are not shown separately as a combined string, in order, for the record’s Target value. To set up the combined value, you create a single string for the fields that are not shown individually, separating the values with spaces. The values must be included in the order, leaving out the values that have separate fields available: Priority, Weight, Port, Target.
    • Note: Depending on your DNS host, the Target field might be called something else, like Content, IP Address, or Target Host.
    • For example, when Priority has a separate field, concatenate only the Weight, Port, and Target values: Target: 1 443 sipdir.online.lync.com
  • For TTL: Set this value to 1 hour or to the equivalent in minutes (60), seconds (3600), etc.
