vvx410 / 5.5.1 User Agent String Change

[Anonymous]

I've noticed this pop up on VVX 410 w/ 5.5.1 and I was just curious if it's a bug.  I coudln't find reference to it in the admin manual, the KB, in previous posts or just by doing Google searches.

We've noticed on some error codes our Polycom phone User Agent strings are changing when the phone generates error codes.

Normally our UAs look like this

0717160259|sip  |0|00|    User-Agent: PolycomVVX-VVX_410-UA/5.5.1.11526

but when an error code is sent (in this case a 404)

0717160259|sip  |0|00|    User-Agent: PolycomSIP-UA/1.2.0

This is pretty reproducable and I don't know if it's a minor bug or something we should be more concerned about.

I've also seen it on SIP/2.0 481 Call Leg/Transaction Does Not Exist response as well.

The phone I have is out of warranty but it looks like 5.5.2 also returns the incorrect User Agent on error codes.

I'll see if we have any devices within the warranty time frame to see if can report this issue since it's reproducable across all phones we've tried. (0004f2 and 64167f)

Hello Eric_P,

so far you are the only customer that I am aware of that has this issue. You can always open a PPI / Pay Per Incident ticket if this is in your interest to get this addressed or simply downgrade to a prior version where this does not appear.

Hello @Kakiman,

welcome back to the Polycom Community.

We fixed this in UC Software 5.6.1 as an example if the issue matches the fix description as this was using specific features.

• EN-34913 SIP 403 Forbidden message to SBC in response to NOTIFY for Event: as-feature-event (Hoteling)

I believe the fix should also be in the next UC Software 5.5.4 and also in UC Software 5.7.0
