SDP in VVX no Detect DTMF

Hello everyone!!

 

I have problem in my configuration to polycom VVX, in the moment to call a number with AutoAttendant and try digit the extension, no works. I make equal test with yealink and works FINE!!! 

 

I read one FAQ to modify the payload of Telephone-Event from 127 to 101 (standard) and nothing, the DTMF no works.

 

Any suggestion?

Attach a config file.

 

Thanks in Adanced.

Regards.

Hello Cesar Barbosa (c3ntro),

welcome to the Polycom Community.

It is always useful to include the currently used UC Software version as issues experienced or a question asked may already be addressed in a newer release.

This also allows yourself and others to check against current software release notes, Administrator Guides or FAQ post’s.

The above is also stated in the "Read First"

Therefore the Polycom VoIP FAQ contains this post here:

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

 

in addition:

 

Oct 7, 2011 Question: Phone unable to send DTMF to an IVR system or how to troubleshoot DTMF issues

Resolution: Please check => here <=

 

The above shows details how to troubleshoot this. So far we have not seen any logs or wireshark traces of a working and not working issue.

Re: SDP in VVX no Detect DTMF

Hi,

 

The version software UC it's 5.2.2.0501 and BootROM 5.4.2.0371. I read the FAQ 'Oct 7, 2011' and no parameters works.

Attach 2 test, one with a polycom VVX600 and second with yealink W52.

 

Thanks.

Best regards!

Hello Cesar Barbosa (c3ntro),

you did not provide any information on the IP's used and in addition the trace was not taken on the phone side so not everything has been captured.

 

In addition 5.2.2 is no longer a supported software version so you should upgrade to 5.5.0 or at least 5.4.4

 

The Invite (if this is the correct thing I am looking at) shows a Payload of 101 being requested but the Yealink is filtered and the Polycom one is missing packets so I suggest you upgrade first and if you still have an issue raise 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. In case this is some sort of an Internet discounter please post your phone's MAC address so I can look up who would be able to support you.
