[asterisk-users] conference calling

[Danny Nicholas]

Greetings listers.

                         I'm running asterisk 1.4.21.2 on SUSE 11.0 using
Polycom 501 phones.  My outgoing connections are Zapata using a TDM401P.
For the most part I can make and receive calls fine except for these 3
issues:

1.       When I call an external conference, the call never bridges and
hangs up after 60-90 seconds.

2.       When I call another number there is a 2-4 second delay before the
callee can hear me.

3.       When I call an external conference and connect, the others cannot
hear me.
