[asterisk-users] Asterisk PBX '&' '||' Grandstream GXP-2000 problem

[J. Espinal]

Hi People,

    We use the Grandstream GXP-2000 phones, firmware 1.1.1.14, 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,
