We need a professional to provide us with the following:
1) Configure three VoIP to GSM gateways (2 GOIP with 8 sim cards each and one Dinstar DWG2000 with 32 sim cards) to complete SIP calls sent from our asterisk. (trunks are already configured and test calls worked so far, we need just to make sure they have two way audio, use g729 codec and are able to carry the CLI sent from our clients, after we deploy the new configuration bellow).
2) Configure inbound routing on our asterisk so our clients can send calls to the trunks that terminate on the VoIP to GSM gateways. As clients can't do registration, we need to be able to do this routing only through their IPs, as we use two layers of security in our gateways and on our asterisk: ip firewall and SIP registration.
3) Make sure the whole setup works: calls complete, they have two way audio, they are able to carry the CLI from our client all the way to the GSM termination, and they have enough quality so we can have an acceptable ASR and ACD).
We are also willing to hire whoever is able to finish this setup as a freelancer contractor, on a monthly or per event fee basis, whatever you prefer, to provide us support with this setup.
