How to add additional SIP profile on ASTPP

Install 2 ASTPP servers following this doc: [login to view URL] ASTPP1 will handle billing, and ASTPP2 here will have a role of freeswitch only (handling calls). ASTPP2 needs to be connected to ASTPP1 DB, so that in ASTPP1 GUI we see also ASTPP2. Users from ASTPP1, must be able to call to user connected on ASTPP2. In ASTPP1 GUI, we must see the customers registered on ASTPP2 (freeswitch), there is an option for that in ASTPP. We suspect, that for interconnecting, freelancer needs to connect ASTPP2 to the DB of ASTPP1 and also create a sip profile of ASTPP2 on ASTPP1, to display the registered customers from ASTPP2 (but that is a hint only); [login to view URL] The done job must be documented from the beginning, very detailed, how the ASTPP's were connected, after installation, what commands are used to achieve the desired result with proofs of successful tests. The doc must be very detailed and clear, as a reference freelancer takes the provided doc for ASTPP installation, so that anyone without a technical knowledge takes the doc, repeats the whole procedure and can validate the job done by a freelancer. When someone from our side repeats and validates the doc of the freelancer, then the project is considered fully done and will be paid. 2 vps servers on centos7 will be provided to freelancer.
