Providers and PBXs
Notes:
If a codec with high bandwidth (e.g. G.711) produces too much interfe-
rence in the call quality, the connection bandwidth might not be suffi-
cient. If these types of disruptions happen frequently, we recommend
you select codecs with a lower band width.
Not every codec is supported by every provider.

DTMF signalling
At DTMF signalling, a sound of two overlapped sound frequencies is
assigned to each digit of the keypad. Here, you must select how the DTMF
signalling is to be transmitted. This is critically depened on the provider and
the transmission path.
