Hi All<br><br>I will do a test call from a soft phone to my mobile. I can speak into my headset and the audio is heard instantly. But if I speak into my mobile there is a 1-2 second delay in the Audio. I am using SIP.<br><br>
I am only finding it in the Zoiper Softphones that we are using. All other phones don't seem to have it present. Sadly the customer is Quite attached to the Zoiper. <br><br>I have set QOS = CS5 for both SIP and RTP packets. Altering these settings has no effect. <br>
<br>We have three 24 port Gigabit switches, with the top switch connecting in the Asterisk Box. Even the stations plugged into the TOP switch have this delay and to the same extent as the other switches. No routers on the loop<br>
<br>I have tried switching the stations to IAX. No effect. I have tried using GSM instead of G711 (alaw). No effect. I have about 30 stations. No change under heavy or light load. <br><br>Is Zoiper any good? Anyone else had these problems?<br>
