Using multiple IP 7000 with laptop

I travel with my IP 7000 phones and use them in environments sucha as hotels and meeting spaces where I do not have wired ethernet or control over the network.


I have 3 IP 7000 phones, two sets of extension mics, polycoms cable that connect the phone to a computer or phone, and PoE connectors.


I am able to connect 1 phone + ext. mics to a phone or laptop.  If C-link is on then it takes ~30 minutes for the phone to recognize the computer.  With C-link off then it connects immediatly.


I am using these phones in a u-shape with up to 30 people and a presentor.  One phone an 2 mics are not enough to pick up the whole room clearly.  In the guide for the IP 7000 phone it has guidance on linking up 3 phones + 2 ext. mics at the end of the chain. 


I followed the setup instructions in the guide but neither of the other phones turned on or worked as a mic or speaker.  The ext. mics at the end of the chain did not turn on either.


I added PoE to the other phones.  They and the ext. mics turned on but the microphones and speakers were not working in tandem with the central phone.  


I tried turning C-link back on but still had no luck with and without power to all phones.


What can I do to make this chain work using a laptop or cell phone connection?

Hello @AnalogToIP ,


welcome to the Poly Community.

Both the communities Must Read First and the FAQ reference the basic minimum information a new or follow up post should contain.

This ensures the questions having to be asked are limited and any new or follow up post contains the right amount of details to ensure any voluntary participant within the community does not spend additional time chasing basic information.

As a reminder the basic information asked for:


  • Provide the exact Software Version of your Phone
  • Provide the Phone Model
  • Provide the Call Platform (aka openSIP,Teams, Skype for Business Online, Skype for Business on Premise, Lync)
  • Additional Poly Infrastructure (RPRM,PDMS or BToE)
  • If applicable provide a backup of the phone in question

UC Software 4.0.0 or later via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup. Please rename into .TXT or Zip the file to attach.
Since UC Software 5.9.0 simply provide this via the Web Interface Diagnostics > Download Support Information Package

  • If possible provide a Log and either attach them or use the Code Tag.Consult the Troubleshooting Section found within the FAQ if applicable
  • If possible provide the MAC Address or Serial of the device
  • Provide details for example if the issue is a day 1 issue or only happened after an upgrade or any other relevant details
  • For questions around Support please check here


Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Poly to have an overview of the current software used. In addition, providing all details at the same time allow us to check logs or look up potential support partners if an issue needs to come into support. It also enables us to verify the entitlement for using features.

Please ensure you always check the FAQ's and/or utilize the community search before posting any new topics or follow up posts.


You are referring to a Poly documentation but do not provide any links to it.


If 2 SSIP7000 are used with the Multi Interface module you can only daisy chain >2< SSIP together. I am not aware of a way to have 3 or more units.

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

Best Regards

Steffen Baier
