Member Function Documentation

void getAudioFormats

(

String &

buf

)

[inline]

Get the formats list This method is thread safe

Parameters:

buf	String to be filled with comma separated list of formats

bool ignorePort

(

)

const [inline]

Get the RTP port change ignore flag

Returns:

True if a port change should not cause an offer change

void initialize	(	const NamedList *	codecs,
		const NamedList *	hacks,
		const NamedList *	general = 0
	)

Update configuration. This method should be called after a configuration file is loaded

Parameters:

codecs	List of supported codecs
hacks	List of hacks
general	List of general settings

ObjList* parse	(	const MimeSdpBody &	sdp,
		String &	addr,
		ObjList *	oldMedia = 0,
		const String &	media = String::empty(),
		bool	force = false
	)

Parse a received SDP body This method is thread safe

Parameters:

sdp	Received SDP body
addr	Remote address
oldMedia	Optional list of existing media (an already existing media will be moved to returned list)
media	Optional expected media type. If not empty this will be the only media type returned (if found)
force	Force updating formats even if incompatible with old ones

Returns:

List of SDPMedia objects, may be NULL

ObjList* parse	(	const MimeSdpBody *	sdp,
		String &	addr,
		ObjList *	oldMedia = 0,
		const String &	media = String::empty(),
		bool	force = false
	)		[inline]

Parse a received SDP body, returns NULL if SDP is not present This method is thread safe

Parameters:

sdp	Pointer to received SDP body
addr	Remote address
oldMedia	Optional list of existing media (an already existing media will be moved to returned list)
media	Optional expected media type. If not empty this will be the only media type returned (if found)
force	Force updating formats even if incompatible with old ones

Returns:

List of SDPMedia objects, may be NULL

int rfc2833

(

)

const [inline]

Get the RFC 2833 offer payload

Returns:

Payload for RFC 2883 telephony events, negative if not offered

bool sdpForward

(

)

const [inline]

True if raw SDP should be added to RTP forward offer

bool secure

(

)

const [inline]

Get the secure offer flag

Returns:
