opal send string

[Adrian Sietsma <adrian_groups@...>]

i have been using 				connection->SendUserInputString()
successfully with a h323 connection.
- the call vectors through to H323Connection::SendUserInputString()

when using a sip connection, the call vectors to 
OpalConnection::SendUserInputString(), and then to 
rfc2833Handler::SendTone()

it then fails at rfc2833.cxx line 106 :

  if (transmitState != TransmitIdle) {
    PTRACE(1, "RFC2833\tAttempt to send tone while currently sending.");
    return FALSE;
  }

any clues as how to send text on a sip connection ?

ps minor error : i think that h323.cxx line 5024
  PTRACE(2, "H323\tSendUserInputTime('" << tone << "', " << duration << 
), using mode " << mode);

should be
  PTRACE(2, "H323\tSendUserInputTone('" << tone << "', " << duration << 
), using mode " << mode);
