Hi, I try to setup the following configuration : - 3CX Phone System software ( ver. 10 or 11, it is not important ) free edition. - 10 SPA 502G phones - 1 x SPA 8800 for our analog lines ( 2 ) and one line from a GSM adapter . Until now ( I do not have the physical devices until now but it will be soon ) I setup a configuration with few extensions and I made some tests with softphones and android devices and everything seems to be ok; I made tests with the phones from the inside network and also from the outside . Now I want to make the next step, e.g. to configure the gateway and the analog lines ( 2 ) , and no need for a SIP provider in this moment. When I add a new gate to the system ( my SPA 8800 ), the only option I have is to select for the brand = Generic and for the model = Gateway Device . After, I must choose the number of ports and I have the first question : I must fill 4 or 8 ?( my opinion is 4 but.... ) When I goes to the Create Outbound Call Rule page , the second question comes : how can I setup a route in 3CX software, for an outbound call based on rules I setup here ? ( e.g. if I want some outbound calls to goes to the analog lines, ports 1 and 2 from the gateway , and other calls for mobiles phones to goes on the third port thru the GSM adapter ). It is the SPA 8800 who make the difference between calls based on the rules ? ( I do not have yet the physical device and I do not see many posts on forum about this subject ). Thanks in advance for any suggestions .
