Ian & Eugen,

Thank you for your responses. I would be happy to create a bug report, although I require some clarification:

1. Should I file one bug report covering the PUBLISH and the BYE issues together, or just one a report for the BYE issue alone?

2. With respect to the BYE issue, the offending message in case of a timeout is

(1) 32 35.745194 192.168.11.177 192.168.11.1 SIP Request: BYE sip:+16172295005 74 125 46 80:24000

Instead, it should look like

(2) 32 35.745194 192.168.11.177 192.168.11.1 SIP Request: BYE sip:17476686228 192 168 11 177:24000

if the record-route field has been set to ensure the proxy stays in the path AND loose routing has not been specified, or

(3) 32 35.745194 192.168.11.177 192.168.11.1 SIP Request: BYE sip:17476686228 72 254 95 107:24000

if the record-route field has been set and loose routing has been specified, or

(4) 32 35.745194 192.168.11.177 198.65.166.131 SIP Request: BYE sip:17476686228 72 254 95 107:24000

if the record-route field has not been set even if an outbound proxy has been specified (please note destination IP), but never

(5) 32 35.745194 192.168.11.177 192.168.11.1 SIP Request: BYE sip:17476686228 proxy01 sipphone com:24000

Right?

I am particularly unsure if I properly understand the IP routing vs. SIP routing mechanism.

Message (4) would fail in my circumstances, but 'siproxd' hopefully sets the record-route field. If not, then it probably should.

Thanks,

Felix

Hi,

I'm not sure but I think you're right - PUBLISH should use outbound proxy.

And there's one another thing I just noticed, which is a problem in
Ekiga - when the transaction times out, the BYE it sends has wrong
routing info. It should use the route set from the 200 response, when
it uses only the outbound proxy, resulting in the 404 responses to
BYE. Someone should bring this up on ekiga-dev/opal-dev.

Please create a bug report.

Hi Ian,

Thank you for the pointer. Indeed it looks like Siproxd never forwards the ACK to Ekiga. Instead it seems to respond with a 408 Timeout (twice). Perhaps you can confirm this reading from the logs below?

While probably insignificant to my problem, I also noticed that Ekiga does not route PUBLISH requests to Siproxd but directly to the Sipphone server (198.65.166.131). Isn't that supposed to go through the proxy, too?

The PUBLISH requests then get swallowed because the packages did not originate on my gateway.

Thank you for your help,

Felix
