Polycom VVX 600 hold issue

We are facing an issue with the Polycom VVX 600 phones on Lync.

IF you put a call on hold , the phone changed the ptime to 80 in the invite, causing issues with our provider ( does not allow ptime > 30).

 

I can not find a parameter to manipulate this value. Is this somehow possible ?

 

We are running on 5.3.0 firmware.

Hello Bart,

welcome to the Polycom Community.

The Software that you are using is no longer supported as we always only support current GA -1 aka 5.4.4 or 5.4.3

 

If you are bound to use the 5.3.x release please upgrade at least to 5.3.3

I can not upgrade because it will not work on our network ( voice-vlan + 802.1x -> upgrade always fails ... )

 

I just tried with one phone on 5.4.4 -> same issue, so not related to firmware. I could also not find anything in the release notes regarding ptime.

Very annoying problem offcourse because nobody using a Polycom phone can place a call on hold or transfer.

Other phones (other vendor) work fine , same as Lync softclient). All use the same MOH wav file.

Hello Bart,

to my knowledge we only have a PTime parameter for the Opus codec.

 

Have you yet worked with a Polycom reseller or can you send me a MAC address from a VVX and your details via community mail so I can get an Polycom SE to contact you in your region?

Re: Polycom VVX 600 hold issue

you can set the timer for each codec :

Payload Size (ms)

And it is set to 20 for all , but when you enable MOH , MOH uses ptime:80 ( 80ms).

SDP info :

a=sendonly
a=rtpmap:8 PCMA/8000
a=rtpmap:127 telephone-event/8000
a=ptime:80

Hey Bart..

 

Just came across this thread.  Where did you find that parameter exactly?  Having the same issue with one of my customers.
