Can't Get audio to IP7000 in VC call when LAN cable attached.

Can't Get audio to IP7000 in VC call when LAN cable attached.

HI all,

Hopefully someone can help today!!


I have an issue where an IP7000 SIP conference phone is connected to our 3rd party vendor's SIP server via the LAN cable into the floor port and connected as a microphone and speaker to an HDX via the WALT cable at the same time. SO if I start a VC call I get no sound from the phone but If I remove the LAN cable the sound comes out of the IP7000 as normal. These are new phone being deployed with new HDX 7000's. We have similar setups around the globe but can't seem to see any issues with the configs. I have to drive 3 hours back tonight (Sunday) to resume fault finding for the morning so any pointers before I get there would be greatly appreciated! Thanks in advance.

Hello ,

welcome to the Polycom Community.

It is always useful to include the currently used software version as issues experienced may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes.

Therefore the Polycom VoIP FAQ contains this post here:

Question: How can I find out my SIP UC Software Version or the BootROM Version of my Phone?
Resolution: Please check here


For the SSIP7000 I recommend the latest UCS 4.0.8 and for the HDX 3.1.6

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