I have recently completed a new install of Yeti and I have a fundamental question about configuring SIP trunks/gateways. We are primarily interested in using Yeti for its SBC, Billing and CDR capability so need to communicate with our asterisk based PBX and our ITSP.
How do we set these trunks up and how do we configure routing between them? My assumption is that we set up the PBX as customer and ITSP as vendor, configure each gateway with the appropriate IP addresses, routing elements, etc.
With all that done, how do we see if the gateways/trunks are registered and communicating?
