Example Back-to-back user agent

constSrf=require('drachtio-srf');constsrf=newSrf();srf.connect({host:'192.168.32.5',port:9022,secret:'cymru'});constSrf=require('drachtio-srf');constsrf=newSrf();srf.invite((req,res)=>{srf.createB2BUA('sip:1234@10.10.100.1',req,res,{localSdpB:req.body}).then(({uas, uac})=>{console.log('call connected');// when one side terminates, hang up the otheruas.on('destroy',()=>{uac.destroy();});uac.on('destroy',()=>{uas.destroy();});return;}).catch((err)=>{console.log(`call failed to connect:${err}`);});});
