We are ordering a standard isdn pri (23 B + 1 B). Our telco allows us to specify that all channels are In/Out (DID/DOD), but that we can limit the max number of DID/DOD. In other words, if we always want to make sure there are 3 channels for outgoing and 3 calls for incoming, we can limit the DID to 20 and DOD to 20. This is on the CO switch side.
How do you configure the Cisco router side to limit the max channels for DID or DOD. The isdn / pri config would still have 23 channels so the config would be something like:
controller T1 0
framing esf
line-code b8zf
channel-group 1 time-slots 1-24 speed 64
clock-source line
interface serial0:23
no ip address
isdn switch-type primary-ni
isdn incoming-voice voice
isdn bchan-number-order ascending
no cdp enable
But how can I tell the router not to attempt more than 20 outgoing (DOD) calls?

You would do something like this:
dial-peer voice 1 pots
port 0:23
max-conn 20
destination-pattern 9.T
dial-peer voice 2 pots
port 0:23
incoming called-number .
max-conn 3
direct-inward-dial

Nitpick:
DP 2 doesn't need port... try to believe :)

I get the concept, but actually I am looking for a max 20 in and a max 20 out so that if either maxes out, at least 3 will be available for the other (of course they could be max out too, but not eliminated).
So I think it should be:
dial-peer voice 1 pots
port 0:23
max-conn 20
destination-pattern 9.T
dial-peer voice 2 pots
port 0:23
incoming called-number .
max-conn 20
direct-inward-dial

Hi Cj,
Yes, this would make sure that at any time there is always at least 3 ports open for EITHER incoming or outgoing. The one I gave was for only incoming. This is probably closer to what you're looking for.
