[asterisk-users] Can't create audio conversation between softphones through Asterisk

Fri Aug 24 09:41:23 CDT 2007

Hello,

I have two user machines, each with a jain-sip-applet-phone installed on it.  I use the following process to try to make a call:

1.  Register each phone with the Asterisk server (working).
2.  Add a contact in each phone which is the other user. (Get a "489 Bad Event" SIP error shown below in red)

Has anyone ever tried using these Jain-sip-applet-phones and got them to work?  I have read up on these errors, and it looks like the 489 error doesn't like the SUBSCRIBE request, while the 488 error doesn't seem to accept the INVITE request made.  I am not sure if this is a problem with Asterisk, incompatibility between Asterisk and the phones, or just the phones.  Any thoughts that may help me resolve these issues would be greatly appreciated.

Thanks very much,

Denis
