[Serusers] Cisco AS 5300 can't send BYE for SER

Hi all.

I have a problem for the following scenario.
When I make a call for PSTN and on hook by PSTN side,
Cisco As can't send BYE for SER.

  01. [UA via Asterisk] dialing "08022223333" -> [SER]
  02. [SER] prefix("0333") and rewritehostport("my.cisco.ip.address:5060")
-> [Cisco]
  03. [Cisco] dial-peer voice 6000 pots, translate-outgoing called from
"033308022223333" to "008022223333"
  04. [Cisco] process an outbound call to "008022223333" -> [e.g. Mobile]
  05. [e.g. Mobile] Catch call
  06. [SER] log CDR start
  07. [Cisco] talking
  08. [e.g. Mobile] On hook and call disconnect
  09. [Cisco] can't send BYE for SER *****why??*****
  10. [UA via Asterisk] On hook
  11. [UA via Asterisk] Send BYE for SER
  12. [SER] log CDR End [Cisco] Call finished

But another scenario, if make a call from PSTN to Asterisk and
on hook by PSTN side, Cisco As send BYE to SER.

  01. [e.g. Mobile] dialing "0377771111(Asterisk user number)"
  02. [Cisco] receive "77771111" call number
  03. [Cisco] dial-peer voice 5000 voip, session target ipv4:
my.ser.ip.address -> [SER]
  04. [SER] process an incoming call to "0377771111" -> [UA via Asterisk]
  05. [UA via Asterisk] Catch call
  06. [SER] log CDR start
  07. [UA via Asterisk] talking
  08. [e.g. Mobile] On hook and call disconnect
  09. [Cisco] Send BYE to SER
  10. [SER] log CDR End [Cisco] Call finished
  11. [UA via Asterisk] receive BYE from SER

And sorry for my diffucult example.

Why Cisco AS 5300 can't send BYE to SER
When PSTN call is disconnected by PSTN side?

    if (search("^(f|From):

      #PSTN Incoming call from Cisco AS 5300 e.g. 0377771111
      rewritehost("my.asterisk.ip.address ");
    };

    lookup("aliases");

    if (!lookup("location")) {

          proxy_challenge("", "0");
          break;
        };
        if (uri=~"^sip:0[0-9]{10}@") {
          # PSTN Outgoing call to Cisco AS 5300 e.g. 08022223333
          prefix("0333");
          rewritehostport("my.cisco.ip.address:5060");
          avp_write("i:45", "inv_timeout");
        } else {
          sl_send_reply("404", "Not Found");
          break;
        };
        consume_credentials();
      };
    };

  };

  if (!t_relay()) {
    sl_reply_error();
  };

}
