<DIV>Hi guys,</DIV>
<DIV> </DIV>
<DIV>I am in the process of establishing a Call Center. I need some suggestions from those who have already worked on such setups using Asterisk. My scenerio is:</DIV>
<DIV> </DIV>
<DIV>US T1 < --- > Asterisk gw 1 < -[gsm compression]-- > Asterisk gw 2 [with TDM10B] < --- > Sip Phones [Xlite]</DIV>
<DIV> </DIV>
<DIV>Calls from US are landing perfectly on the Xlite and tdm10b, and vice versa. However I am having some trouble as mentioned below:</DIV>
<DIV> </DIV>
<DIV>1. Call quality on Tdm10b is good, but sometimes on Xlite, sound becomes choppy (like the voice missed for few mili secs). I am using jitterbuffer=no is IAX.conf (if set to yes, sounds becomes more choppy).</DIV>
<DIV>2. There is lot of echo during the conferencing [on Xlite], when in a room more than 4 people talk at the same time.</DIV>
<DIV>3. I am using GSM compression on the Asterisk, and my Xlite also uses GSM, but when I switch from GSM to iLBC in the server (Xlite still using GSM), sound qulaity degrades.</DIV>
<DIV> </DIV>
<DIV>Plz recommend your suggestions, and is Xlite good for Call Center ?? </DIV>
<DIV> </DIV>
<DIV>Further the echo that I am getting, can be caused due to normal headphones ??? can some guide me which headphone is best in terms of echo cancelling and noise reductions. Did anyone tried the Plantronics PLA-H161N (<A href="http://www.thephonesource.com/PLA-H161N.htm">http://www.thephonesource.com/PLA-H161N.htm</A>) ??</DIV>
<DIV> </DIV>
