Question

Each flash phone takes a separate number on a sip server

Hello, is it possible to setup the FMG to register each flash phone number on separate sip server for bidirectional call from flash to sip phones, and from sip phones (which registered on sip server 3cx) to flash app directly (not 1 gateway number ).

For example, on my sip server 3cx there is 100, 101, 102 phone numbers, which is registered by FMG and associated witch each flash phone. When I call to 100 from my internal sip server number, it should ring on flash phone 100. And when I call from flash (internal number 100) to 120 (sip server 3cx number – 3cxphome) it should ring on 3cxPhone directly from that flash application without any gateway number.

If required, multiple SIP accounts can be specified in conf/SIP.xml. However, it is not absolutely necessary to have multiple registrations to same SIP server. Following explains routing calls using single SIP account.

Custom caller IDs are specified by using desired value of callerIdNumber/Name in createCall API  in corresponding main.asc on FMS. The sample "telephony" app already leverages these optional parameters as a reference.   


For incoming call:

    - On SIP server, enable call routing for desired set of dialed numbers to FMG. 

    - On FMG, ensure that the calls are routing the FMS application by specifying in workflow.xml. For example, a default entry within "sipGatewayContext" forwards any dialed 4 digit dialed number starting with "1" to RTMP profile_default

For troubleshooting, look out for error messages in logs (FMG & FMS applications logs) as hints !

Is there possibility to have several simultaneous conversations between flash phone apps (more then one) and SIP accounts on 3cx server using just one SIP gateway account at SIP server?

Yes, having large multiple calls using single SIP account is very much a reality.

Although, I am not sure about things specific to 3CX however on Asterisk a normal SIP account is equally capable.That said, some host PBXs may have separate set of settings for such accounts. For example cisco Call Manager provides settings to restrict number of simultaneous calls on such a SIP account
