Disallowed SIP
Methods
When a dialog is started with another SIP endpoint, the other endpoint should include an Allow header telling us what SIP
methods the endpoint implements. However, some endpoint either do not include an Allow header or lie about what
methods they implement. In the former case, the gateway makes the assumption that the endpoint support all known SIP
methods. If you know that your SIP endpoint does not provide support for a specific method, then you may provide a list of
methods that your endpoint does not implement in the disallowed_ methods option. Note that if your endpoint is truthful
with its Allow header, then there is need to set this option.
Shrink Caller ID
The shrinkcallerid function removes '(', ' ', ')', non-trailing '.', and '-' not in square brackets. For example, the caller id value
555.5555 becomes 5555555 when this option is enabled. Disabling this option results in no modification of the caller id
value, which is necessary when the caller id represents something that must be preserved. By default this option is on.
