How can I create a custom SIP Proxy?

Problem:

Solution:

You can create your own branded SIP Proxy and configure your softphone and devices with your domain. It is necessary for you to create a sub domain and edit your DNS record. Please contact your DNS hosting provider or system admin and have them create a sub domain like sip.yourdomain.com and edit the DNS so that it points to our SIP Proxy servers. Here is zone configuration that you need to provide the person who handles this for you:

$ORIGIN yourdomain.com
sip IN CNAME sip.varphonex.com

Each DNS hosting provider has different methods to create and point sub domains. Please contact your DNS provider's technical support for help to create and re-direct the sub domain as we have mentioned above. The re-direct must be in the CNAME format in order to survive future IP address changes.

Once you have completed this configuration run nslookup for the sub domain and it should show something like this:

Non-authoritative answer:
Name: sip.mydomain.com
Address: 208.239.76.170

Once you have confirmed your DNS changes, you will need to enter your customer domain name in the "SIP Realm" field on the "Reseller Info" page. You will now be able to use the custom domain in the configuration of your SIP UA's.
