hi, I need to provide a high availability feature for our sip A/S. The current idea is to add a parameter into some headers of the sip message such as the route header, request-uri etc.(it is added to multiple headers because external UA may modify some headers such as request-uri)
The parameter will indicate which A/S in the cluster is handling that dialog. This parameter will be used by a router to route in-dialog messages to the corresponding A/S. The problem comes when the A/S has crashed and the router needs to route a message to another A/S. It needs to route the message to some A/S2 & the parameter for that dialog needs to be modified accordingly. However,some header's such as route can be set only for initial requests and should not be modified later. My question is which header can be used/modified reliably for the above purpose of storing the parameter? regards, Nanda ****************************************************************************************** This email and its attachments contain confidential information from HUAWEI, which is intended only for the person or entity whose address is listed above.
