DNS and SMTP Setup Guide
This article explains what needs to be done to point your desired FQDN at our servers.
General Info
The primary portal default URL is core1-lhr.lmwhvoip.com with IP Address 141.147.113.128.
The secondary portal default URL is core3-lhr.lmwhvoip.com with IP Address 141.147.91.92.
For the purpose of this guide we will assume that your domain name you are using for the portal is mydomain.com.
It is recommended to setup 2 subdomains, one for the primary portal and one for the backup (secondary) portal.
IMPORTANT: SIP traffic will automatically failover from one portal to another using DNS SRV, however HTTP traffic does not automatically failover. This is why it is recommended to setup 2 sub domains, as if HTTP traffic fails to the primary URL you can continue to use the backup URL.
For this guide, we will assume the subdomains below are chosen:
portal.mydomain.com for the primary portal.
backup.mydomain.com for the secondary portal.
TIP: You don't need to use the subdomains "portal" and "backup" if you don't want to, you can use any text you want.
Create DNS Records for the Portal
When creating the DNS records you can either create a CNAME record or an A record. a CNAME record will point your subdomain to our URL whereas an A record will point it straight to the IP Address.
A CNAME can be better because it means if the IP address of the default URL changes you won't have to update your portal URL, however creating a CNAME record means our URL will be exposed if anyone does a DNS lookup on your portal URL.
A Record Example Configuration:
| Type | Domain Name | Value | TTL |
| A | portal.mydomain.com | 141.147.113.128 | 1800 |
| A | backup.mydomain.com | 141.147.91.92 | 1800 |
CNAME Record Example Configuration
| Type | Domain Name | Value | TTL |
| CNAME | portal.mydomain.com | core1-lhr.lmwhvoip.com | 1800 |
| CNAME | backup.mydomain.com | core3-lhr.lmwhvoip.com | 1800 |
Email Sending
If you want to send email from your own domain, then by default our servers will attempt to send as you, however this will likely result in errors and emails going to junk.
To prevent this you need to provide SMTP details for the email you wish you to use. This is normally managed as part of your onboarding however if this is still outstanding please submit a ticket containing your SMTP details to help.luminatewholesale.com (or raise a ticket in the phone portal.
IMPORTANT: The moment we upload your SMTP details then any other emails will stop working.
Please ensure that you provide accurate details, as if incorrect details are supplied it will prevent email from working at all on your account until it is fixed.
