[Asterisk-Users] Keypad disabled on AriaVoice SIP phone

[Ian Pattison]

I'm not sure about the chipset but they do appear to be similar... with the exception of IAX2 support which mine do not have, SIP, H.323 and MGCP only.

A bit more detail that I've uncovered... if I call into asterisk from an outside line and connect to my SIP phone I get DTMF tones passed in both directions. If I call from my SIP phone to an internal Zap extension DTMF is passed properly. But if I call from my SIP phone to an external phone (via a ZAP FXO channel) the keypad shuts down and nothing is passed. Here's the important part of my extensions.conf:

exten => _9NXXNXXXXXX,1,Dial(Zap/2/${EXTEN:1})

Thanks,

Ian

Are these the same as YUXIN phones sold by eezeePhone.com? Do they have
PA1688 Chipset?

This does not look like a problem of the phones, but something to do
with Asterisk Dial plan. Are you using 'Answer' or 'Dial' command?

1)If you are usind Dial command, do not use T or t flags
2)DTMF mode Inband works only for Ulaw. If You use any other codecs, use
RFC2833

Hi All,

I've got a couple of AriaVoice C-301P SIP phones connecting to * and
have a bit of a problem. I can dial out with no problem but once *
bridges the call to another channel (such as a Zap channel to the PSTN
or an internal Analog phone) it appears that the keypad is then disabled
which keeps me from navigating other peoples IVR trees. I've seen some
ramblings on DTMF relay (usually when applied to Cisco products) but
don't know if that's my issue at all. I've tried both RFC2833 and Inband
Audio for DTMF handling with identical results. It literally appears
that the keypad is being disabled after dialling. 

I've attempted to contact the vendor of the phones several times and
have been unsuccessful in reaching anyone.

Anyone had a similar experience?

Thanks,
