Hi,
Is this a PBX response ? or is it coming from the device (gateway) ?
If it is from the PBX What sort of INVITE generated this ?
And finally what version of PBX are you using please ?
I have 3.0.2295.0 of 3cx and are evaluating and it ticks all my boxes with the call queueing in the enterprise version
The Gateway is a Quintum Tenor DX2010 which i know is not on the supported device list but I have to use as I need to integrate with Cantata IP fax devices both software and hardware based.
I have not yet actually received the DX2010 but have bee advised that it can only register with 1 SIP Proxy but can carry out a failover operation from one device to the next. The requiment for it to do this us that one of the standard SIP errors is received when attempting to pass the call to the SIP proxy see below.

Scenario: Single pstn E1 with predefined DIDs serving 3 entities. 2 of these are on IP side using SIP and 1 legacy PBX on E1.
IPPbx (SIP) : 3CX Phone System for Windows
FoIP Server(SIP) : Cantata Brooktrout SR140 and TR1034 fax SIP or H323
