Hi,

doc/supplementaryservices-api.txt says nothing about return values of 
SupplementeryServices.Initiate method (or that the method can take SS 
requests in addition to USSD). Can the API designer/implementer fix this 
please?

string, variant Initiate(string command)

			Sends a USSD command string to the network
			initiating a session.  When the request is handled
			by the appropriate node of the network, the
			method returns the response or an appropriate
			error.  The network may be awaiting further response
			from the ME after returning from this method and no
			new command can be initiated until this one is
			cancelled or ended.

			Possible Errors: [service].Error.Timedout
			Possible Errors: [service].Error.Canceled

Regards,
Alex
