transcoding and conferencing. Cisco recommends that the media resource IP address be static and unique for
MCS7890-C1.
For Cisco ISR2901 gateway, the media resource IP address is the same as the ISR2901 gateway IP address.Note
DNS and Hostname Resolution
This document does not provide detailed information on DNS. You should have a thorough understanding of
DNS before you use it with your Cisco Business Edition 3000 system. DNS is optional; you do not have to
use a DNS server unless you plan to resolve hostnames for your Cisco Business Edition 3000 server or gateway.
If you include a hostname for the server or gateway on the Network or Gateway page and you must use DNS,
make sure that you map the hostname(s) to the IP address(es) on the DNS server for both forward and reverse
DNS resolution. Cisco recommends that you perform this task before you add or edit the hostname in the
Cisco Business Edition 3000 GUIs.
The current version of the Cisco Business Edition 3000 does not require a DNS server; however, it is configured
for future requirements such as SIP trunks.
Cisco recommends that you do not configure Cisco Business Edition 3000 to use DNS.Note
SFTP Server
Cisco allows you to use any SFTP server product but recommends SFTP products that are certified with Cisco
through the Cisco Technology Developer Partner program (CTDP). CTDP partners, such as GlobalSCAPE,
certify their products with a specified release of your software.
For information on using GlobalSCAPE with supported Cisco Unified Communications versions, refer to the
following URL:
http://www.globalscape.com/gsftps/cisco.aspx
Cisco uses the following servers for internal testing. Be aware that you may use the servers, but you must first
contact the appropriate vendor for support at the following URLs:
• Open SSH (refer to http://sshwindows.sourceforge.net/)
• Cygwin (refer to http://www.cygwin.com/)
• Titan (refer to http://www.titanftp.com/)
Cisco does not support using the SFTP product, freeFTPd, because of the file size limit on this SFTP
product. For issues with third-party products that have not been certified through the CTDP process,
contact the third-party vendor for support.
Caution
You can use a SFTP server to complete the following tasks:
• Upload the upgrade file from the SFTP server to the Cisco Business Edition 3000 server before you
perform an upgrade
