asterisk users - Apr 2005 - ZAP - outgoing call using different D-Channel each time ?

Hi Fellow Asteriskians,

Currently I am having an Asterisk installation piggy-backed behind an 
"intelligent" voice-switch that does the LCR, over E1's using
Digium TE410p

The problem is that Asterisk always starts channel 1 if the channel is free, 
and only switches to channel 2 if channel 1 is in use...

Can the behaviour be changed so that outgoing calls using ZAP channels are 
on a rotary basis, like 1..30 and then back to 1 for each outgoing call?  It 
has namely happened that channel 1 on the other side "hung" in the
"Free"
state which severely impacted my operations as you can imagine...

Hope somebody can shed some light on this. I can't seem to find the option 
in any of the zap conf files and I have been trying to meddle with the 
chan_zap.c source file to no avail...

Thanks for your help
Walter

Don't you mean B-Channel? You only need 1 D-channel.

I use Dial(ZAP/R1d/2815551212,30) on all our zap calls and this will go in
order on the span.
