Connecting TA FXS Gateway to TA FXO Gateway
1. Introduction
For companies that have geographically distributed office, there is no need for them to install a PBX at the remote offices. Users could simply set up TA FXS Gateway and TA FXO Gateway in remote offices without any SIP server. This scenario allows organization with remote location to access FXO(PSTN) trunks through IP network.
In this guide, we introduce how to connect TA FXS Gateway (located in US) and TA FXO Gateway (located in China). After connecting, users in US could make local calls through PSTN trunk located in China and save international charges.
