[Asterisk-Users] Can't find capi.conf syntax to use 2 controllers

[Prima Informatica]

Hello,

I'm trying to configure asterisk with 2 controller (one is a AVM fxusb, 
the other is AVM fcpci). Each controller is bound to a separate BRI ISDN 
line.

The two modules are correctly loaded and configured by capinit:

# capiinit status
1 fxusb      running  fritz-usb        A1 3.10-02 2
2 fcpci      running  fritz-pci        A1 3.11-02 0xe800 10

I've configure capi.conf as follows:

[interfaces]
msn=041534xxxx,041534yyyy
incomingmsn=*
controller=1,2
softdtmf=0
devices=2,2

Asterisk reports:

*CLI> capi info
Contr1: 2 B channels total, 2 B channels free.
Contr2: 2 B channels total, 2 B channels free.

So, apparently everthing is fine, but incoming calls form second msn are 
not detected by asterisk.

I not able to find where support for multiple controllers is documented.

May anyone help please?

Thanks in advance.
