Hello,
I have a problem with the same values of Hangupcause in two different cases.
First, then asterisk makes call to busy GSM Port, GW1202 reports “switching equipment congestion 503 Service unavailable” which is set in “Advanced SIP Settings -> Parsing and Compatibility->Hangup Cause Code” and that is OK.
Second, then asterisk makes call to mobile and call is canceled on phone without answer. Asterisk will receive same value of Hangupcause (“switching equipment congestion 503 Service unavailable”).
If I try to call the same mobile phone but through another SIP provider and cancel it on mobile, asterisk will receive correct code “17 user busy 486 Busy here”
SIP Endpoints ->Advanced:Signaling Settings->Add Q.850 Reason Headers: YES
and setting use_q850_reason=yes on GW1202 trunk doesn’t solve the problem.
Any suggestions?

I have a similar problem, one of the SIM cards go to a state where all calls directed to it ends up in 503 error and I have to reboot the device. It's very annoying.
