Setup Custom SIP Domain

2 min readVoice

@Hosted users/extensions are able to connect their end devices like SIP Phones, Softphones, etc, directly to the @Hosted platform. By default, when you set up a , we will assign you with a SIP Domain. You can view your customised SIP Domain from the Atomic portal by navigating to the Settings page of a specific account that is subscribed to a @Hosted Service Plan and by selecting the Hosted Voice tab.

To customize the SIP domain with your own branding, you’ll need access to your domain’s DNS settings. Add an A Record using the details below.

Please contact our support team to obtain the IP address assigned to your services. Once you have it, log in to your DNS provider’s portal and point your desired domain to this IP address.

Let’s say your provided SIP Domain is http://acme.voice.atomcomm.com and you want to change it to be hosted.acme.com.au and you own and have access to the DNS records for acme.com.au. Login to you DNS providers website and add a new A Record with the below information:
markup
Type: A
Host: hosted (or whatever name you would like to use)
Points to: {{the ip provided by our support team}}
TTL: 1 Hour

Once the A Record has been updated (it can take anywhere between a couple of minutes to a couple of hours for it to go live), you can then provide your end customers with your own SIP Domain to connect their SIP devices to your Hosted Voice environment.

Custom SIP Domains must be unique for each account. This means if your Custom SIP Domain is hosted.acme.com, you cannot re-use this for the next account. This value must be unique.
