Hello,

 

I found that a VVX 300 phone is not providing a ringback tone (after receiving a 180 Ringing SIP reply) when its blind transfered. That happens for UCS 5.3.0 or higher.

 

Here is the test scenario:

 

VVX 300 calls SPIP 650 (there is ringback here in call cases)

SPIP 650 answer the call, press "Transfer" then "Blind" softkey and enter the destination

Destination rings and VVX 300 visualy show that the call is going to another destination (there is no ringback here when UCS is 5.3.0 or greater).

 

I've tested the same scenario with 5 different UCS versions, wih the same VVX 300 hardware and configuration.

Here are the results:

 

5.4.0.5841 = No Ringback. Visual indication is present (Line key blinking green, arrow in the line icon)
5.3.1.0436 = No Ringback. Visual indication is present (Line key blinking green, arrow in the line icon)
5.3.0.12074 = No Ringback. Visual indication is present (Line key blinking green, arrow in the line icon)
5.2.3.0192 = Ringback and Visual indication is present
5.2.0.8330 = Ringback and Visual indication is present

 

Is this a know "bug"? Or it can be related with some expected change of behavior starting in UCS 5.3.0?

I can't find any related information on both UCS 5.3.0 or 5.4.0 Administrator Guide or in these versions release notes.

 

Thanks.

Joao Arruda

Thanks CDEng,

 

call.switchToLocalRingbackWithoutRTP="1"

 

That really fixed the issue for VVXs running UCS >= 5.3

Hello @Christophe_Sewan,

 

welcome to the Polycom Community.

Both the community's 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 Polycom 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

  • 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 if the issue is a day 1 issue or only happened after an upgrade or any other relevant details

Whilst providing some of these details may not directly impact any possible answer the community can provide, it does enable Polycom 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 a 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.
