IP Station Duo UC4.0.12.xx, how to add "tone tone.dtmf.rfc2833Payload="127"

[Anonymous]

We use IP Station Duo (SIP), registered to Cisco Call Manger, it got issue with external DTMF IVR.

I found detail from this knowledgebase

http://community.polycom.com/t5/VoIP/FAQ-Phone-unable-to-send-DTMF-to-an-IVR-system-or-how-to/td-p/4...

I have been up load the "dtmf_payload_127.cfg" still did not working, or which configuration path that I can do revise ?

config_files.cfg, web.cfg,devices_settings.cfg or phone_local.cfg ?    

Cisco engineer checked on voice gateway and ask to change DTMF tone to be 127:

 <dtmf>
  <tone tone.dtmf.rfc2833Payload="127"/>
 </dtmf>

Hello IT_easycompare,

welcome to the Polycom Community.

The community's VoIP FAQ contains this post here:

May 25, 2017 Question: Can I create a backup of my current configuration?

Resolution:Since UC Software 4.0.0 or later a backup can be created via the Web Interface Utilities > Phone Backup & Restore > Phone Backup > Phone Backup

Utilizing the above simple instructions enables you to check within your backup <Web section if the added configuration is present.

As you are using a software later than 3.2.0 the payload type requested by the Cisco Engineer is already used.

I suggest to use the rest of the FAQ post to troubleshoot this.

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

Hello IT_easycompare,

As already outlined the Payload is 127 as a standard and therefore if set agin is removed as we are already applying this value.

The backup of the configuration will only show parameters that differ from the standard.

Ok,

1. exported  web file and put the revised payload to 101, 

web>

  tone.dtmf.onTime="100"
  tone.dtmf.rfc2833Payload="101"

 />

2. inport again.

 Then it worked right now, Thanks.
