[osmocom-analog] SIP connector for osmocom-analog?

Hello all! I have been enjoying osmocom-analog with my AMPS phones for the last few days and was wondering if there has been any work done for SIP connectivity with analog phones? I see there is 'osmo-sip-connector' software from my searches but as far as I can tell, there is no similar software of osmocom-analog. Thanks, Mike
