- | - Update your system! If you install AsteriskNOW, and don't perform a "yum upgrade", you will be running a version of the dahdi-dummy module that depends on a hardware RTC. Xen does not have a hardware RTC. This is fixed in CentOS/Asterisk packages available using yum, so simply update. | + | - Update your system!

+ | ===== Meetme/Conferences not working? ===== | ||
+ | |||
+ | The symptom of this problem is: you have properly configured a Conference, but dialing the conference number | ||
+ | from an internal numer (i.e. extension), the Asterisk woman tells you: | ||
+ | <code> | ||
+ | That is not a valid conference number | ||
+ | </code> | ||
+ | |||
+ | Conferences requires proper generated timing, and the solution to this problem is the same as | ||
+ | the solution to MoH/ringtone problems above. Update your dahdi-modules and instruct asterisk to generate | ||
+ | internal timing from dahdi-dummy. | ||

+ | ===== Using Nortel telephones, is it possible? ===== | ||
+ | |||
+ | YES! Nortel proprietary IP telephones uses a communication protocol called Unistim. This protocol has been reverse-engineered for the purpose of interoperabillity (thus legal at least in Europe), and the results are implemented in the chan_unistim Asterisk module. I separated this in to its own page: | ||

+ | |||
+ | At least the i2004, i2002, i2007 hardphones and the i2050 softphone are supported. | ||
