mikhail Posted February 6, 2007 Report Share Posted February 6, 2007 A gateway should obtain a function to finish an existing call. Is it possible if INVITE contained Authorization? Is there some way to config BYE Authorization? The situation is that pbx should answer 401 or 407 for INVITE, but I need some setings to know for sure that pbx will accept BYE without AUTH and it wont send 401 or 407 for my BYE.

Vodia PBX Posted February 6, 2007 Report Share Posted February 6, 2007 Trunks can answer challenges, also for BYE request. You need to set up the username and password in the trunk for that. However, challenging BYE has the big problem that is might not be possible to hang up a call. That is very dangerous. The PBX does not challenge BYE. The Call-ID is the "token" for the call. If you want to protect others to send a BYE (DoS), use TLS transport layer. Quote Link to comment Share on other sites More sharing options...
mikhail Posted February 7, 2007 Author Report Share Posted February 7, 2007 Thanks. But can u recommend some other way to hang up the call from the gateway? As I suggest The most easier way is to sen BYE in both directions - But if you say that it "might not be possible to hang up a call." May be there is more reliable way?

Vodia PBX Posted February 7, 2007 Report Share Posted February 7, 2007 I don't get it... If the gateway wants to hang up, of course it should send a BYE. Where is the problem? Quote Link to comment Share on other sites More sharing options...
mikhail Posted February 8, 2007 Author Report Share Posted February 8, 2007 The problem is that pbx can answer "Unauthorized" for BYE from Gateway(and I know that some pbx do so) and gatway knows nothing about password. It is rather expectable becouse it answers "Unauthorized" for INVITE. Well you have told me that "The PBX does not challenge BYE". Actually I just need some official confirmation that it is so. (or config settings) for latest January pbx version. We are to install pbxnsip but don`t know for shure that it will work correctly in our network just becouse of this "small point".

Vodia PBX Posted February 8, 2007 Report Share Posted February 8, 2007 Ok, lets clarify this: For outgoing requests coming from a trunk, the PBX is able to answer BYE challenges. For incoming requests that are sent to a trunk, the PBX does not challenge BYE requests. Quote Link to comment Share on other sites More sharing options...
