<div>I have a remote office with only one analog phone, we have an FXS port to a "black phone" and one FXO port for 911 calls.</div>
<div> </div>
<div>The extesnion is 9227, the configuration is enclosed below...</div>
<div> </div>
<div>When on a call there is "static" or background noise, and occasionally one way transmission (typically the IP phone calling him can not hear the black phone and the black phone can hear just fine). Other times the call drops all together. Yet other times, everythign is just peachy and we can make 6-8 calls in a row that work great. So I was thinking it might be a QoS issue. Any hints or leads are appreciated.

<div>Here is the gateway configuration (H323, 2620 running 12.2.23F):</div>

<p>I was wondering if the bandwidth 16 is enough for the voice call. It is a dry-pair T1 connection and only one phone on the site.<br>Any help is appreciated, and thank you in advnace</p>
