Disallowed SIP Methods
When speaking back to other SIP peers, the other peers should
include an "Allow" header to tell us the implementation of the SIP
method. However, some peers do not include "Allow" headers or
forge the methods they implement. In this case, the gateway will
assume that the peer supports all known SIP methods. If you know
that your SIP peer does not provide support for a specific method,
then you may need to provide a list of methods that the peer does
not implement in "disallowed methods".
Notice:
If your peer is real, then there is no need to set this option
Shrink Caller ID
The function can 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.
