When the system needs to send a SIP URI in a header, the information used for the @host part of SIP URI is taken from the following settings (listed in order of priority, starting with the highest):
Source/Setting |
Descriptions |
Short Code |
Short codes used to route calls to a SIP line can specify the host for the calls To and R-URI headers.
This is done in the short code's Telephone Number field by adding the host as a quoted suffix. For example, N"@example.com". The value must be enclosed in " " quotation marks to prevent any part being interpreted as short code wildcard characters. |
Local Domain Name |
If set, this setting is used for the host part the From, Contact and Diversion headers sent by the system, overriding the ITSP Domain Name below. It is also used for the PAI header if Use Domain for PAI is selected on the SIP line. |
ITSP Domain Name |
If set, this setting is used for the host part of the From, To, Diversion and R-URI headers sent by the system. |
ITSP Proxy Address |
This setting is used for the host part of most headers sent by the system if none of the values above are set. However, if several addresses are set here, then either the ITSP Domain Name and/or Local Domain Name settings must be used. |
