Voxalot / SIP Broker Support Forums - View Single Post - My telephone starts to ring when I hang off after an incoming call

No matter what the terminal is. I tried with several terminals (PAP2T, Linksys3102, Siemens gigaset 470 IP and x-lite softphone) before contacting keyyo's support.

They said that this matter very well known to asterisk community. Older Asterisk versions used to accept "BYE" command without authentification and that allowed a third party to disconnect your call. Asterisk fixed that in 1.4.2. which causes "BYE" commands to be rejected when not authentified. The call is then, not terminated (It's terminated at voxalot but not on the VSP secured 1.4.2+ plateform ... since the call is not terminated, an invite is then sent by asterisk/keyyo which causes the terminal to ring again

Asterisk did not comply to standards in regard to command authentification before 1.4.2. Now it does. This is requiered for reliable communications

I have this problem since they upgraded in june... if you whish to test, you could try to pick up a keyyo's account (It's free at www . keyyo . fr) (keyyo is one of the major VSPs in France).

Voxalot need to upgrade since more a more VSP would be upgrading...
