WDE Sip EndPoint send DTMF to MCP

[cavagnaro]

Hi guys
Having an issue here...
I have a request to make WDE agents to be able to call a GVP Application, a small project that collects agents Input and stores the data.
Now my first issue was, that when agent tried to send DTMF I got an error from SIP Server:

[quote]
EventError
(Bad parameter passed to function)
[/quote]


So I added this option to the agent DN:

rfc-2976-dtmf = true

So, ok no more error there. But now, when I send the DTMF nothing happens. SIPServer sends this:

Any clue? I would expect configuration between them to be clear but seems not...

Thanks!

I would suggest to return the option rfc-2976-dtmf to false and configure the extension with option sip-cti-control with value dtmf,hold,talk

HTH!

[cavagnaro]

Yeah, tried that too but docs say that dtmf value is no longer valid on latest WDE.
Will give it a shot anyway.

Thanks

And did it help or not? In case using in-band RTP try to check your codec configuration or just make a network sniff to see what happened.
