When creating an XML bulk import file:
The domain name must be unique. The name is referred to by other elements.
You cannot create a domain with a <domainType> of sip and the <defaultDomain> containing the value true.
The values in <domainType> are case-sensitive and must appear exactly the same as the values appear in the System Manager user interface.
Example
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<sipdomainFullTOList>
<SipdomainFullTO>
<notes>this is a test</notes>
<defaultDomain>false</defaultDomain>
<domainName>avaya.com</domainName>
<domainType>sip</domainType>
<name>avaya.com</name>
</SipdomainFullTO>
<SipdomainFullTO>
<notes>this is another test</notes>
<defaultDomain>false</defaultDomain>
<domainName>avaya2.com</domainName>
<domainType>sip</domainType>
<name>avaya2.com</name>
</SipdomainFullTO>
</sipdomainFullTOList>
