Methods in Dial Plan
In this table, enumerate which SIP methods the Dial Plan should handle.
The ACK, PRACK, CANCEL, BYE, NOTIFY, UPDATE and INFO methods can’t be han-
dled by the Dial Plan. These methods are routed in other ways according to the session they
belong to.
This table is only available when the Advanced SIP Routing or the SIP Trunking module
has been installed.
Method
Enter the method name. Standard SIP methods can be found in RFC 3261.

Create

REGISTER in Dial Plan
REGISTER requests can be handled by the Dial Plan, but require some special processing.
The REGISTER request is the standard method to connect a SIP username to an IP address.
For this, the To header is used to convey the SIP username, and the Request-URI is used to
tell the server to which the request should be sent. For this reason, To headers in REGISTER
requests forwarded through the Dial Plan may no longer match the server to which they are
sent.
When Rewrite To headers for REGISTER requests passed through the Dial Plan is
selected, the domain part of the To header is rewritten to match the new Request-URI.
