Fixed Problems

• Skip speech related events when DTMF input is in progress.
• Fixed a possible segfault on processing of the header field Logging-Tag having an empty [no] value.

Configuration Parameters

Miscellaneous

• Log not only status code but also status text extracted from received HTTP responses.
• Upgraded the gRPC library to 1.30.3 version.
