I have phone system DB 9.1 with Audio and WebConf version 2_01_GA_b5.

In order for people to connect to a audio conf they need to enter the access code and press # on the phone.
Most of the time this works fine.
Once in a while the # is not recognized and they cannot connect.
Does anyone know if there is a way to allow someone to enter the code and still join the conf without pressing (or the system recognizing) the #?
Do diff phones send diff # signals?
To get them in I have to transfer them to the conf enter the code and # for them, say their name # then hang up.

Any ideas??
Thank you
