AEQ PHOENIX AUDIOCODECS APPLICATION NOTE 0 E AEQ Phoenix Studio units through Internet Complex scenario configuration Through LOCAL network s DHCP not used manual NAT Using SIP Direct mode The most convenient and reliable way to connect an IP codec to a remote one through Internet is by means of a dedicated exclusive Internet access DSL cable modem In this application note a way to achieve the same result will be proposed when this is not possible as Internet access is shared with other equipments connected within a managed LOCAL LAN and DHCP is not available or convenient This application note describes the recommended procedure when AEQ SIP Proxy is not reachable or we don t want to use it and SIP signaling is used from end to end with no servers involved As we need to get access to Internet a shared resource in this case it is mandatory to contact the network administrator in order to have the required resources enabled and gather all the necessary information This document shows the specific steps to make this connection possible in the most general way possible although some verification procedures have been omitted in order to ease the reading and some particular situations may be easier to solve that the presented one For a detailed explanation of every step and for details on how to configure other options that may be more convenient for other cases the reading of the rest of application notes as well as2. the status call status and the different phases it steps through CALLING CONNECTING SYNCHRONIZING and finally CONNECTED Verify that the SYNC LED situated under the CALL key is lit in green color as an indication that the communication has been correctly established and synchronized You should hear audio from Phoenix Master in the headphones Established connection detail Be sure that ON AIR is activated for that communications channel in order to allow the full duplex audio transmission from to the associated XLR connectors Once the connection is well established it can be repeated as many times as necessary varying the audio coding algorithm until the best possible quality is reached given the network conditions Menu CH1 STATUS gt CODING List The audio coding algorithm lists are created by entering MAIN STATUS gt SYSTEM gt 10 SIP CODEC PROFILES 5 MAKING A CALL TO OTHER PHOENIX CODEC OR TO A N ACIP COMPLIANT CODEC The calls to Phoenix Master or Phoenix Master 2 have been automatically answered To make a manual call to other codec it is necessary to configure the second one the same way if it is connected to a managed local network or in a simpler way if it is connected to Internet directly through an ADSL router or cable modem with DHCP server as explained in the corresponding application notes ANOA or ANOB Once the reporter unit can connect properly to Phoenix Master 2 you can create in the phone boo
