I have an obi box has it’s own 9 digit address..Just want to receive calls with that 9 digit address (ie sip#) or IP address if able..I have a sip from voip to make calls…Just a thought that someone might know how to..
Assuming your Obi ATA is connected to VoIP.ms, it can receive calls made to the SIP URI of the form did-number@sip.voip.ms, as documented here: https://wiki.voip.ms/article/SIP_URI#Using_your_DID_number
