Hello,

I have an issue that I don't understand.
IP Office answers 400 on SIP invites.
I suspect malformed INVITE, but I don't find why.
Other calls are OK, just some callers, always the same, are refused.
I noticed errors with topology, but other calls are OK.
Any help is welcome.

Here are monitor traces...

Make sure all the users have a properly configured SIP settings.

Under Users/SIP

SIP Name = full 10 digit phone number
SIP Disply = Name you want displayed.
Contact = Extension Number

SIP Calls will fail from users that do not have those fields properly configured.

Hi Travis,
Thank you for your answer.
Sorry, I was not clear enough.
Issue is on incoming calls, essentially from some mobile phones.
In general calls are working.
Destination is an huntgroup.

Hello,
It's the tag of the INVITE who is too long for IPO.
You can use a SBC to make a SIP manipulation to shorten it.

Thank you JCH-19.
That was the issue.

IP Office only supports 80 characters long until 11.1.2.3 that increases the limit to 150 chars.
I upgraded system to 11.1.2.3, everything is OK since then.
