[asterisk-users] ISDN Error Code 42

[Nitesh Divecha]

Hello All,

Just got one general question on ISDN error code 42. As per Cisco docs 
and Wiki 
(http://www.voip-info.org/wiki/view/Asterisk+variable+hangupcause) it 
says "Switch equipment Congestion" with explanation "The destination 
cannot be reached because the network switching equipment is temporarily 
overloaded"...

My question is are the calls treated as "Failed" and I will be pulled 
away from the routing? Is this similar to ISDN error code 34's?

Please help...

Cheers,
Nitesh
