Techniques for efficient messaging client communication are described. In one embodiment, an apparatus may comprise a client front-end component of a messaging server operative to receive a protocol connect packet from a messaging client, the protocol connect packet initiating a client authentication process with the messaging client; and receive a message package from the messaging client, the message package received during the client authentication process; a client authentication component operative to perform the client authentication process with the messaging client; and a client message queueing component operative to queue the message package in an authorization-holding message queue in response to the message package being received during the client authentication process. Other embodiments are described and claimed.

Various of the disclosed embodiments improve the initial codec selection in a Voice Over Internet Protocol (VOIP) connection. Particularly, rather than select an initial codec for the connection arbitrarily or based on data measured during the connection, embodiments analyze attributes of data exchanged prior to connection establishment to identify the appropriate initial codec. Attributes of the offer message transmission and acknowledgement may be used to infer channel quality. Signal strength, the existence of a WiFi connection, previous codecs used, etc., may also be taken into consideration. Latency measurements may be used as a proxy for measuring available bandwidth. Based on these factors, a codec having appropriate attributes may be selected. Traditional rate shaping methods may be applied subsequent to the initial codec selection.
