[cisco-nas] 7 / 10 digit matching

[Michael Tague]

Hi,

We are in the US and are trying to make outbound 7 & 10 digit dialing work
correctly on a Cisco 2400 IAD.   For a while we have been using outbound
dial-peers with the following destination patterns:

#11	destination-pattern [2-9]11		(911, 411, etc)
#12	destination-pattern [2-9]......	(7 digit dialing)
#13   destination-pattern 1..........	(1+ long distance dialing)
#14   destination-pattern 011T		(011 International calling)

They work well.   Specifically, if you dial a local 7 digit number, it will
immediately match and make the call, or, if you dial 1+10 digits (for Long
Distance), it too will match as soon as the last digit (the 11th) is dialed.

However, in our area, some are used to dialing a ten digit number, area-code
+ 7 digit number.   We would like to make that work.   At first I added two
dial-peers with these destination patterns (note: 502 and 812 are local area
codes):

#15	destination-pattern 502[2-9]......
#16   destination-pattern 812[2-9]......

thinking that the explicit 502 and 812 prefixes would favor dial-peers #15
and #16 over #12, but that didn't happen.  Instead, as soon as the dialer
hits the 7th digit, dial-peer #12 kicks in and a bad number is dialed.

I looked at Reg-Ex on the destination-pattern string, but couldn't see an
how to exclude 502 or 812.

Anyone on the list have some wisdom on this?

We wound up using these patterns:

#102  destination-pattern [^0158]......
#104  destination-pattern 502[2-9]......
#106  destination-pattern 50[^2]....
#108  destination-pattern 5[^0].....
#110  destination-pattern 812[2-9]......
#112  destination-pattern 81[^2]....
#114  destination-pattern 8[^1].....

which work but make what we are doing rather obscure.   Any suggestions?

Thanks,
Michael
