<b>Ämne:</b> [cisco-voip] fast tone<o:p></o:p></span></p>
</div>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>today and many times before i had users complain they get
fast tone. they dial number and get the fast tone. it seems to be
only for outgoing call. to be sure i advised them to write down time and
called number.<br>
<br>
what is causing that?<br>
<br>
per "cisco callmanager fundamental", read below.<br>
<br>
if it is bandwidth issue, which bandwidth?<br>
phone to vg?<br>
vg to pri?<br>
<br>
how can i see it?<br>
<br>
thanks guys in advance. <o:p></o:p></p>

<p>Like IP precedence, regions play an important role in ensuring the quality
of voice calls within your network. Regions allow you to constrain the codecs
selected when one device calls another. Most often, you use regions to limit
the bandwidth used when calls are placed between devices connected by an IP
WAN. However, you can also use regions as a way of providing higher voice
quality at the expense of network bandwidth for a preferred class of users.<o:p></o:p></p>
<p>When you define a new region, Cisco CallManager Administration asks you to
define the compression type used for calls between devices within the region.
You also define, on a region-by-region basis, compression types used for calls
between the region you are creating and all other regions.<o:p></o:p></p>
<p>You associate regions with device pools. All devices contained in a given
device pool belong to the region associated with that device pool. When an
endpoint in one device pool calls an endpoint in another, the codec used is
constrained to what is defined in the region. If, for some reason, one of the
endpoints in the call cannot encode the voice stream according to the specified
codec, CallManager attempts to introduce a transcoder (see Chapter 5) to allow
the endpoints to communicate."<o:p></o:p></p>
