supports the AES encryption algorithm, which is an ietf rfc 3711 standard.
The media encryption technology of the Cisco router is combined with the media encryption features of the Cisco uniied CallManager software and the Cisco uniied IP phone, which fully guarantees the security of gateway-to-Gateway calls and IP-to-Gateway calls. Therefore, you can provide secure analog call, fax call, or IP Call and gateway call based on the gateway interface type that the media is terminated. With Transpor

bandwidth efficiency of media encryption using RTP is higher than that of IPSec.
The media encryption feature of the Cisco Access Router is also compatible with Cisco CallManager and media encryption features on Cisco IP phones to protect calls from IP phones in the first-level MGCP mode to gateways. This allows the customer to perform secure common call, analog call, or fax call between the IP phone and the gateway, depending on the Gateway Interface Type of the terminal media. The voice encry

SqlCommand cmd = newSqlCommand ("select * from stu", conn );
Conn. Open ();
SqlDataReader rdr = cmd. ExecuteReader ();
Conn. close ();
When the SqlDataAdapter is executed, it automatically hits the database and does not use the ExecuteReader method of Command to assign values. After the execution, the connection is automatically disconnected.
