I added the "permit=" statement at the end of echolink.conf to limit access to club members only. I did this to eliminate the plague of ungracious and irresponsible skimmers, dropins and lurkers. Refer to http://ohnosec.org/drupal/node/56 for details. However, I discovered that there is a limit on the number of entries in the "permit=" statement. If you add more than 30 calls, the system will disconnect after about 10 seconds and respond with an RTCP TIMEOUT . Multiple "permit=" statements do not work - only the first statement is acknowledged. [The limitation is in line 154 of chan_echolink.c - "#define EL_MAX_CALL_LIST 30"] If you know of an alternate method to create a lengthy whitelist for Echolink in app_rpt, please advise.
