[Asterisk-Users] Problem with INVITE's being sent

[Álvaro Palma]

I've being testing a couple of GrandStream ATA 286 which with no reason 
start responding 486 Busy to all new incoming INVITES. They are 
connected to an Asterisk installation as SIP client. Running ethereal 
between them, I could notice that, for some reason unknown for me at 
this time, Asterisk sends some stranges INVITE's AFTER the communication 
has been established and acknowledged (even after the REINVITES have 
been processed by both ends).

Does anybody know the reason of this burst of this "out of scheme" 
INVITEs? I guess that maybe they're confusing the ATA, setting it BUSY
in consecuence.

Thanks a lot for your help
