Hello community!,

I was trying to figure out if there is a way to re-route **failed calls** instead of just hanging up them

I know that there is a specific variable: DIALSTATUS that takes part of the DIAL command, but i dont know how to use it correctly ☹. _(Maybe i am wrong…)_

A exten =\> example would help **a lot**

**Best regards!**

There is an example, in the sample extensions.conf, of rerouting to voice mail. SImply replace voice mail by Dial.

In practice, you may want to look at HANGUPCAUSE, as well.

@david551  
I found the example:

[stdexten]  
${ARG1} - Device(s) to ring

exten =\> \_X.,n,Set(LOCAL(dev)=${ARG1})

exten =\> \_X.,n,Dial(${dev},20)

I dont really get the idea ☹ _(Maybe this wasn’t the example)_

If my first post was not clear, then let me give a example

Lets say that i have 2 gateways,  
GW 1 = Less cost but less prefixes to dial  
GW 2 = High cost and dials everything

You know where this goes

Im trying to Dial always to GW1, but, if it does not take the call, then, i need to re-route the call to GW2

This code isn’t tested, it’s just an example.

```auto
exten => s,1,dial(gateway1/${ARG1)
same => n,Gotoif($[${DIALSTATUS} : "CONGESTION|CHANUNAVAIL"])?GATEWAY2
same => n,playtones(busy)
same => n,busy(16)
same => n,Hangup()
same => n(GATEWAY2),Dial(gateway2/${ARG1})

```
