How Avaya SBC replies to OPTION message

[redyps90210]

All,

Can you enlighten me how Avaya SBC responds to SIP OPTIONs message from the Session Manager?

This is necessary for the SIP Entity Monitoring in System Manager and it looks like our SBC doesn't respond to it.

Also is this just between the SM and SBC? Some says that the OPTIONS are intended to the carrier or far-end PBX and the SBC is just passing it.

Thanks!

To My knowledge The Avaya SBC does not respond to SIP OPTIONS and instead passes that on to the Carrier.

In our environment, the Carrier responds with a 405 "Method Not Allowed" which is interpreted as a valid response and so the Link is considered UP.

I hope that helps.
