GoIP GSM Gateway configuration with SIP and PBX

Job ID: 30658021

Budget: $30 – $250 USD

I need to have e GoIP GSM Gateway configured to work with SIP so that I can call through a SIP softapp routing the calls through the SIM card in the GSM gateway. This is for personal use, not a business so not sure if a PBX is required.
