<div align="justify"><small>Hi People,<br><br> We use the Grandstream GXP-2000 phones, firmware <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://1.1.1.14/" target="_blank">1.1.1.14</a>, Asterisk PBX, Slackware Linux
10.2, loaded on a Intel(R) Pentium(R) 4 CPU 2.66GHz Box... The issues that we are experiencing involves our Telephone Operator's/Receptionist whom answer multiple incoming calls... As an example.., when they answer line 1 and Line 2 starts to ring they would ask the person on line 1 to "hold" and proceed to answer line 2 and forward line 2 to to the requested extension. The problem is when they attempt to pick line 1 off the "hold" in order to handle that call, line 1 is either dropped or the Grandstream Phone freezes and the user is forced to rest the phone. The situation persist whenever there are multiple lines active with incoming calls and upon answering one, placing the line on hold and attempting to answer the other lines active calls will be dropped the the phone just hangs/freezes. We know that the call is dropped because the people call back complaining about being hung up on!!!! We have had our dedicated T1 (for voice only) tested several times and it is good. We have had the Asterisk PBX completely redone and gone over thoroughly and are at the point where we are suspecting the configuration file for the Grandstream GXP-2000 Telephone as the culprit. We would like to know what suggestions anyone out there might have if any... Thanks,

<div>Are you using G.729? Last I heard, grandstreams could only have one call via G.729 at a time. It had something to do with the licensing that they used, I think. Just a thought...</div></div>
