SIP 404 error message on incoming call
« on: November 28, 2012, 09:05:19 AM »
Hi,

I would appreciate if someone could help me to understand why the ICP 3300 version 8.0.9.20 replies with error message "SIP 404 Not Found" when receiving a SIP INVITE from an AudioCodes SBC. Below is the SIP INVITE sent by the SBC:

2012-11-28  12:56:04  Network->STS  SSP   Level = 3   Unique ID = 0

And below is the error returned by the Mitel:

The architecture is as follow:

The full Mitel log is attached to this post.

Thanks for your assistance. Have a good day

Nothing stands out from the logs there with a quick look.

Is there any chance of upgrading this system to at least 4.1 where SIP functionality was greatly improved and resolved a lot of issues?

Thx for your feedback. Unfortunately it is not possible to upgrade this ICP 3300 (no more support contract).
