Hi,

I just installed a second GSM dongle in my Asterisk box.  
In the dongle.conf I had the following line to help routing incoming calls from that GSM number to an internal extension.

exten=+351961XXXXXX (X where obfuscated by real numbers)  
I had an inbound route to route this number to an internal extension.

NOW, I have another dongle, and another GSM number.  
I can not route the 2nd number to another internal extension.

So,  
GSM number +351961XXXXXX --\> extension 122  
GSM number +351965XXXXXX --\> extension 123

How can I configure the dongle.conf ?  
I think there is nothing more to do in the “inbound routes”.

Hi,  
The documentation on [wiki.e1550.mobi/doku.php?id=usage#incoming\_calls](http://wiki.e1550.mobi/doku.php?id=usage#incoming_calls) says chan\_dongle will use by default that the subscriber number stored on the sim. Only when the subscriber number is not available it will use the exten variable in chan\_dongle.conf.

So you have to create extensions with the phonenumber from the simcard.

> On incoming call, chan\_dongle tries to find matching exten in defined context (see dongle.conf). There is 3 different exten to search, in the following order:
> 
> ```
> Subscriber Number stored in SIM.
> Number defined in variable exten in dongle.conf
> s exten
