Re: Spam:*, [reSIProcate] Question on Accept Header Validiation...
Scott,
I have to agree with you - it doesn't sound right.
An example: Cisco gateways support a type gtd/signalling
that encodes the contents
of the ISDN message as a content type and ships it with the
INVITE if it is enabled but
the handling is set to optional.
It is used for transparent ISDN signalling across a SIP
network between gateways. It
is also used by their TCL environment and their soft
switches for controlling aspects
of an ISDN/SS7 call that can not be controlled/set via SIP.
If you reject messages with this then a lot of functionality
is sacraficed for inter-
operability with other devices. From what I have been using
I know that Polycom
phones quietly ignore it and the Asterisk PBX ignores it but
logs a message of
an unknown content type.
