[SIPForum-discussion] In which scenario Proxy will generate CANCEL ?

[ridhuan yusof]

Hi,

Due to no responding, the proxy will send the CANCEL to B-Party after
timeout reach and B-Party will respond with 200OK. Then proxy send 408
Request Timeout to A-Party and should be respond with ACK.

Regards,
Ridhuan
