Hi,

If A and B are doing topology hiding, having the outbound server adding a Route hdr does not help at all....As when the BYE gets to B, it should have in RURI the B address, without no Route hdr.

So, you need to change the RURI to make it point to B.

When you say "only about 50% BYE messages can befilled in with the correct RURI" -- what happens with the rest of the BYEs ??

Hi all,

I have one outbound proxy and two proxy servers A and B where proxy server A
is master and B is standby.
The outbound proxy is responsible for forwarding messages to the master
proxy server A. The master proxy server
A calls topology_hiding() on initial INVITE messages.  When the master proxy
server A is down, the standby proxy
server B will take over the future requests. Since the standby proxy server
B does not have
the "did information (topology hiding)" generated by the master proxy server
A, the outbound proxy will add
a route header "<sip:B;lr>" to BYE message before forwarding a BYE message
to the standby proxy server B. However,
with SIPp (about 20 calls per second), only about 50% BYE messages can be
filled in with the correct RURI.
The other BYE messages are with the route header "<sip:B;lr>" added by the
outbound proxy as the RURI.

Can someone give me a hint to address this issue? thanks.

Best regards,
Chen-Che
