[Asterisk-Users] ztdummy configuration help

[kurt x]

Upon setting up and configuring the my extension.conf, meetme.conf and
following the instruction outlined at this web page:
http://www.voip-info.org/wiki-Asterisk+timer+ztdummy

I get the following errors when calling the meetme number.

Executing Wait("SIP/216.53.118.2-f41196e0", "1") in new stack

Any help is greatly appreciated.
