Error Message - Harmful or Erroneous?

[BobbyMitel]

Hi All -  We started having SIP error messages after our vendor upgraded the 3300's back in Dec 2016.  I reported it in Feb 2016 and it's still happening even though they say that Mitel fixed it.  What is it?  Is it harmful?

Guess knowing about your sip devices might help.

Unless people are complaining of call issues or failures, the SSPGetMinSEHeaderInSipMsg error is erroneous.

The other one may or may not be of interest... what is 192.168.56.100 and do you have a valid extension 2657 and is it working?
