Hi,

You can do that with this dialplan :

<extension name='MessageNet'>
    <condition field='${destination_number}' expression='^9(\d+)'>
        <action application='bridge' data='sofia/gateway/your MessageNet gateway name/$1'/>
    </condition>
</extension>

<extension name='Skype'>
    <condition field='${destination_number}' expression='^7(\d+)'>
        <action application='bridge' data='sofia/gateway/your Skype gateway name/$1'/>
    </condition>
</extension>

<extension name='TelecomItalia'>
    <condition>
        <action application='bridge' data='sofia/gateway/your TelecomItalia gateway name/${destination_number}'/>
    </condition>
</extension>

I have 3 gateways:
Telecom Italia on an analogue adapter

MessageNet (sip provider)
Skype

 

How can I select gateway by a prefix THAT THEN GETS DROPPED before Dialing..

 

Example I would like to have

All calls beginning with 9 Sent to MessageNet , DROPPING THE “9”

All calls beginning with 7 sent to Skype, dropping the “7”

Otherwise use telecom
