The problem has been discussed multiple times over the last several weeks.
To recap, there is two things needed to incure the problem:
 1. cisco 7960 phone (it discards packets with uneven timestamps)
 2. asterisk had an iax problem that was fixed about a month ago assoicated
    with uneven timestamps. The distant iax system will need to be upgraded
    to fairly recent code.
