Asterisk ss7 query

Hi All,

Need urgent suggestion, Can asterisk-ss7 chan_ss7 or LibSS7 send signaling over to MSC (1 point code) and media (voice) over to mediagw (another point code) to which asterisk server is directly physically linked.

Is it possible that Physical connectivity and signaling link-sets will be established with MGW while MSC-Server will be responsible for call control in asterisk-ss7 chan_ss7 or LibSS7.

Please Let me know. Really appreciated if anyone will share some doc. web link or conf file.

Thanks in advance,
