Enhanced 911 for OpenSIP

[alexxst]

Hello,

I'm trying to configure my VVX/Trio phones working in Generic SIP mode (ver: 6.4.1.2280) to send the switch MAC address & Port ID to server in SIP REGISTER request ('X-switch-info' header).

I've set below, but see nothing in REGISTER message.

feature.E911.enabled="1"
locInfo.source="LLDP" 

Expected to a similar behavior like with Yealink phones, am I missing something?

Hello @alexxst ,

Welcome to the Poly Community. Pictures inside the topic need to be approved by a moderator before they appear.

From our latest 6.4.0 Admin Guide >here<

• feature.E911.enabled
  0 (default) - Disable the E.911 feature.

  1 - Enable the E.911 feature.

  The INVITE sent for emergency calls from the phone includes the geolocation header defined in RFC 6442 and PIDF presence element as specified in RFC3863 with a GEOPRIV location object specified in RFC4119 for in Open SIP environments.

I would only expect an INVITE to include this.

If you still believe we are violating an RFC or there is a bug please go ahead and open a support ticket in your region and/or if the phone is out of warranty our team should explain to you who to contact to pay for PPI/PayPerIncident support.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Hello @alexxst ,

I have since then looked into this and it seems you only need to enable the following for the phone to send the x-switch-info in its register message:

<web voIpProt.SIP.header.switchInfo.enable="1"/>

I am getting a Doc Bug raised as I believe the Admin guide states this should be enabled by default.

Enabling this will send the register message with the Switch Port. To my own personal knowledge, this was added for our Partner Zoom. 

Any issues, if you are not using Zoom, for the supported use case please follow this up as explained via our support organisation.
