SIP Message-No Licenses

[TelecomsTim]

Does anyone know the message that the SBC/IPO will send back to the SIP provide in the event that all licenses are being used?

I would guess it would be a 486 (user busy) but if you have had any of you no for sure I would appreciate if you could confirm.

More likely it would return 500 or 503.

Hmm, yeah 503 seems quite likely..

503 Service Unavailable
The server is undergoing maintenance or is temporarily overloaded and so cannot process the request. A "Retry-After" header field may specify when the client may reattempt its request.

If anyone knows for certain please confirm as I need to feed this info back into our SIP team and I don't currently have the lab set up to test myself.

I guess it depends if you have less licenses than trunk members. If you've got 15 licenses and a trunk of 10, the 11th call get a busy. If you've got 10 licenses and a trunk of 15 members, the 11th call would probably get a 503.
