Tech Talk: Branch Office Trunk Sharing | Yeastar PBX System

[@geesondomeinnojavier7479]

Does it require a SIM Module to route the calls locally?

[@YeastarTechnicalChannel]

Hi, PBX supports some type of trunks. GSM trunk which uses SIM Module is a type of trunk that you can use on PBX to make the call. Btw, you can contact the sip trunk provider if you want to use sip trunk.

Can this be done the same on a P series PBX?

[@YeastarTechnicalChannel]

Yes, it is similar. But for the PBX integration, we have an easier way to realize it. We can use FQDN on PBX to support the account trunks for another PBX to register directly. And then you can set a similar Inbound To Outbound setting. Any questions feel free to create a ticket on support.yeastar.com.

@@ameenadoosh2885 I think you can probably try our LCS(Linkus Cloud Service) if you're going to use Linkus.
