- I have a conceptual question regarding
dial peer / destination-patterns.
If a install has the requirement here in
Chi town that they want to hit a 9 to be
routed offnet to Ameritech/SBC and be able
to do either 7 or 11 digit dialing (1+10)
how do you set the destination patterns?
I can get a destination pattern of 9T to
work fine, but if I want to get specific,
say because the Ameritech switch only will
accept 10 digits or more so I would need
to prepend - prefix the local area code to
7 digit calls, a 9T would not work for this
and would seem to interfere with a exact
dial peer / destination pattern match for
911, though I don't dare test that.
I was thinking that I would need four dial
peer w/ destination pattern aimed at the
correct FXO ports, but when I do this, the
result just doesn't work right.
--- Example ---
The first dial peer / destination pattern
is for 7 digits dialing. It should strip
the 9 by default. It prepends the local
area code to send to the switch.
dial-peer voice 9 pots
destination-pattern 9.......
prefix 847
port 1/1/1
The second dial peer / destination pattern
is for 11 digits dialing. It should strip
the 9 and 1 by default sending the remain
10 digits to Ameritech/SBC's switch.
dial-peer voice 91 pots
destination-pattern 91..........
port 1/1/1
The third dial peer / destination pattern
is for international dialing, or calling
codes. It should strip the 9 by default
sending the remaining digits to the switch
after 10 seconds of not hearing digits.
dial-peer voice 90 pots
destination-pattern 9T
port 1/1/1
The fourth dial peer / destination pattern
is for 911. No digits should be stripped
as no wild cards are used. 911 should be
sent to the switch, but on a different
port.
dial-peer voice 911 pots
destination-pattern 911
port 1/1/0
Testing by calling 918005551212 results in
a call being placed for 1800555 as if it
matched dial-peer 1 as the best match.
Ameritech/SBC has pleasant messages for the
result. . .
When I do a show dialplan number <E164>,
both dial-peers 1,2,3 show as if it they
can match.
If I do the same show dialplan against 911,
the results are that all four are valid.
Where am I going wrong?
