4135 num Q23

Post by pixel »

Hello,

I have the following problem with a 4135 phone.

When I'm in audio conference center (accross a GSM SIP Gateway) if I need to dial "1" following by the hash key for a dialog in french or "2" for a dialog in English, it's not work, nothing happens.

Codec use = G729

4135 is configured DTMF=RFC2833, if I try DTMF=INBAND, when I dial "1" digit sent is "11"

I try with an another king of phone, like polycom IP 6000, with this device it's work fine.

Maybe my is due to the firmware of 4135 release (REV. 1.5.5 JUN 29 2011)?
