Hi!<br>so after using the "sip show channels" commands i can see that most of the the communication are under ulaw format and one or two are under gsm, do you guys know a way to force the system to use only ulaw, is it a good idea and is it gonna solve my static noise issue?<br>
actually, the caller and the called hear the static noise just when handset is used, once i use the speaker it's gone.<br>actual situation:<br>-once i use the handset to dial i can here the noise.<br>-i have the same model polycom phone configured with another server (asterisk 1.4), and guess what no noise at all.<br>
any guess!<br><br><br><div class="gmail_quote">2010/3/27 khalid touati <span dir="ltr"><<a href="mailto:khalidtouati@gmail.com">khalidtouati@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

<div><br>> it should be some commands that can give me a better idea about the<br>> codecs, if anyone know them, please help!<br><br></div>Use "sip show channels" and "iax show channels" and look at the Format<br>
column.<br><br>About the Polycom devices: Others will have to help you there. I have no<br>good guess why you might have the issue only on speakerphone, but not in<br>handset mode. Could it maybe be some kind of electrical grounding issue<br>
(instead of something caused by transcoding)?<br>
