AEQ PHOENIX AUDIOCODECS APPLICATION NOTE 0 D Connecting AEQ Phoenix Mobile units via Internet complex scenario configuration Through LOCAL network s DHCP not used manual NAT Making use of AEQ Proxy SIP Adapted to Phoenix Mobile User Interface 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 also describes the recommended procedure when AEQ SIP Proxy is used where both equipments involved in the communication are registered easing the task of finding the remote IP address when it is variable or unknown 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 options2. you can create for convenience new entries in the call book Menu gt ADVANCED gt 2 Contacts with the name and URI of the remote unit the same way it was done for Phoenix Master in the previous chapter and then easily make calls to them You can of course also send the calls without having previously created a Call Book entry from the main screen by pressing Menu to go to the Wizard Select the Call to line press Select and URI is selected Then type the desired destination URI in the line below select Enter URI then press OK and type the URI in For this communications mode based on a SIP server you only need to introduce the name of the unit for example Phoenix_123 The call indications optical and also acoustical if enabled will be activated at the destination codec that will either wait for the user to answer the call or automatically off hook if this mode is enabled and then establish the connection The LED next to TX PROG should become green lit and audio should be heard through the headphones The three first screen lines should be Connected lt equipment name gt sip aeq es lt coding scheme gt APLICACIONES ELECTRONICAS QUASAR S A TEL 34 91 686 13 00 FAX 34 91 686 44 92 E mail aeqsales aeq es Web WWW aCq CU For more information and other configuration options please read the User Manual and Application Notes corresponding to other scenarios If you still have doubts
