Hi everyone. I need some help.
The problem we are having is that "voIpProt.SIP.conference.address" works fine on Private lines, but when we attempt to use it on a line that is Shared, the phone reverts back to using the local conference on the phone.
Also, after a local conference on a shared line ends, the line begins to blink even though there are no active calls. The only way to stop it is to reprovision/restart all the phone at the same time.
So very strange.
We are using Freeswitch 1.6.15 (64bit)
UC Software Version 5.9.1.0615

Hello @Tricom ,
welcome to the Polycom Community.
I have just tested this on a VVX450 and it works fine with a shared line. The next step would be a ticket.
In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you.
End Customers are unable to open a ticket directly with Polycom support.
If this is some sort of an Internet discounter providing your MAC address or your Polycom devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Polycom device from.
If the unit is no longer within warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Just to be clear, you said you tried this on a vvx 450 using the hosted conference room option instead of the local conference option utilizing "voIpProt.SIP.conference.address="3015@xxx.xxx.xxx.xxx" and a Shared line, and NOT a Private registered line?
Is this correct?
I don't have a reseller. I bought them on Amazon. How do I send you my MAC addresses? Am I do just post them here?

I found something interesting.
If I use the following parameters.
reg.1.type="private" voIpProt.SIP.conference.address="3015@mydomian.com" reg.1.server.1.specialInterop="Standard"
The phone can set up the conference on the conferencing agent just fine.
However, if I use:
reg.1.type="shared" voIpProt.SIP.conference.address="3015@mydomian.com" reg.1.server.1.specialInterop="Standard"
The phone can only conference locally and not on the server.
If I use:
reg.1.type="shared" voIpProt.SIP.conference.address="3015@mydomian.com" reg.1.server.1.specialInterop="Genband"
The phone sets up the conference as it should on the server.
This would be a solution, however, using Genband is not an option since it causes other features not to work for me properly, but looks closer to being an internal issue with the phone software.

Hello @Tricom ,
If you want Polycom support to look at this we need the MAC address of the phone so we can outline who would provide the support to you.

Hello ,
welcome to the Poly Community.
Both the communitys Must Read First and the community's 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,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 post’s.
In order to raise a support ticket, you need to work with your Poly reseller as they need to do this for you.
End Customers are unable to open a ticket directly with Poly support.
If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.
