SIPB-710 — SIP method recognition message
The SIP proxy has read a SIP request start line with the method and the URI printed in the message.
The D-level message only reports success of parsing.
The W-level message means that the proxy cannot understand the method read. The current version of the proxy allows to pass such requests, however, it guarantees no further support to them. If the method, for instance, needs to open some data channels, it will fail. Please, report the error to the authors.
