You can create spans with channels from any other span (as long as the
signaling is the same).

[span zt xorcomSpan]
; channels from 1.5 trunks
fxo-channel => 1-12

Then dial:

<action application="bridge" data="freetdm/xorcomSpan/a/$1/>

You can also just define a group for those channels and use the group
for dialing.

[span zt xorcomTrunk1]
trunk_type => FXO
group => xorcomg1
fxo-channels => 1-8

[span zt xorcomTrunk2]
trunk_type => FXO
group => xorcomg1
fxo-channels => 9-12

Then dial using the group name.

<action application="bridge" data="freetdm/xorcomg1/a/$1/>

This means spans and groups are strings within the same name space (as
far as hunting is concerned), and you should not make them conflict.
