Hi All, When adding a SIP provider to 3CX there's an option for simultaneous calls. I had it set to 1 and tried calling outbound from 2 extensions using the same SIP provider. This failed and only allowed me to call out from one extension. I changed it to 100 and was then able to call out from both extensions and the caller ID number showed up. Should the SIP provider be able to tell me exactly how many simultaneous calls can be made? Or is it just defined by the number I enter?
