3. When incalls is set to 2-call will be forwarded to the number specified by the “forwardnum“ option in the GSM network.-the simcards must support the forwarding options, otherwise this operation will fail4. When incalls is set to 3-the call will be forwarded to the Mizu server specified by the “outserverip” setting in the gateway configuration.-on the server, the call will be forwarded to the “gsminccalled” number (SimPlatform configuration). If the “gsminccaller” option is filled with a validphone number, than the callernumber will change accordingly. Otherwise the caller number will be the original caller. The ip caller address can be changedwith the “gsminccallerip” option. (thus you can simulate the routing from a predefined user)5. When incalls is set to 4-the caller will be asked to enter the target number (handled with dtmf), and the call will be forwarded to that number-the prompt played to ask the target number can be set by the “playdtmfreqfile” setting. This will have to point to a PCM 8000kHz, 8 bit mono wave audiofile.-the prompt to be played if the forwarding has failed can be specified by the “playdtmffail” setting. When the forwarding is in progress, the“playdtmfforward” file will be played to the user.-the call will arrive to the server with the ‘222’ techprefix, and you can setup a separate routing roule for this tecprefixA possibe callflow for calls arrived to a working simcard in” inccals 3” mode:original caller initiate callcall routed by gsm networkcall arrives to our simcardconverting from gsm to h323call routed to GKon routing: caller will be converted to “gsminccaller”, called will be converted to “gsminccalled”call needs to be forwarded to “sip2h323”sip2h323 module doing the protocoll conversion from h323 to sipcall arrives to SIP modulerouting will decide the proper routingclient sip endpoint is created and call forwarded to the target gatewaycall will be handled by the called gatewaycall forwarded to the final user4.8.7.
