Retransmission from the UAC should not be suppressed by sending 100 by Stateless proxy.It should only be done by Stateful proxy. Stateless proxy will only forward the request, it will not retransmit it. Therefore the retransmission from the UA is desirable. Statless proxy will forward all the retransmissions it receives. > another question about the REGISTER message, i have CISCO 2610XM gateway, > this gateway sends register messages every 3.6 seconds due to it's > configuration, do i have to implement a Timer to remove the domain it > register for every 3.6 seconds, or i can just add it once, and everytime it > sends REGISTER message again i can ignore it??? >If you send a 2xx response to the REGISTER request, then in theory at >least you are responsible for making sure that the expiration of the >registration is extended to match the expiration in your response (you >didn't say how long it is requesting).
