On a polycom 600 which is working perfectly otherwise, I am unable to use DTMF with IVR or such - not even to dialout of a Sipura setup elsewhere. Other phones (analogue connected to ATA) are accepted. I suspect the phone is not using rfc2833 but I don't know how to specify that it should use it (not available on the http configuration). -------------- next part -------------- An HTML attachment was scrubbed...
