You can also add an additional DPA 7630/7610 to achieve a higher level of
redundancy or fault tolerance. In this situation, you can use two DPA 7630/7610

to fail, the Octel system would use only the lines that were still operational,
allowing voice mail to function normally.
If you want to use this configuration, be sure to review the information about
