I am running version 2.0.1.1624 on Windows SBS 2003 SP1. When a call comes in no auto attendant prompts are heard. If I type the extension I want the call is connected and it is possible to have a conversation.
I can also call the auto attendant from the phone and hear audio prompts fine.
I am using a Sonicwall router with the most current firmware, I am aware of the issues with Sonicwall and have tried three versions of their firmware, the most recent (SonicOS Enhanced 3.2.3.0-6e) which is newer than the "problem" firmware in the Wiki seems to be the best. Even using the one sugested on the Wiki gave the same results, but the most current seems to give better call quality.
I must not have the proper ports opened although I hae opened 506-5062 for SIP as well as the defualt Sonicwall "VOIP" port group.
Are there any other ports that need to be opened?
