Summary:                    app_sms hangs on a call sending an sms
Description: 
I'm not sure it's a bug, I'm new to asterisk and I not found anything on
this.
Sending an sms to Telecom Italia smsc (4210) causes app_sms to send the
sms and then keeps the line busy waiting for something to happen.
I have modified apps_sms.c in the sms_process function commenting the 1734
line:

//		h->idle = 0;

This makes app_sms to send the sms and then drop the line because the idle
reaches the 80000 value.
Repeat: I'm not sure this is a bug and is more likely to have something
wrong with me.

This is actually likely a problem with disconnect supervision on your
analog lines. This may or may not be enabled on the lines. Make sure you're
using KS (kewlstart) signaling. This may also be something that needs to be
enabled by your telco on the line to allow disconnect supervision to
happen. I'd err on the side of this not being a bug.
