Incoming registration on sip trunk

[Snahvp]

Hi

Is there a way to setup a sip trunk for incoming registration on a cloud pbx? We want to connect a local SBC with cloud pbx. So the easiest way would be to let the SBC register to the cloud pbx.

Kind regards
Hans

Wouldnt it be easier to have it the other way around to have the PBX register with the SBC? This is usually the case, as we would consider the SBC to be a SIP trunk and connect to it.

Sure but would it be possible? Then we don't need to setup any port forwarding on customer site.
