[cisco-voip] Quest for the best H.323 dial-peer configuration

[kapil atrish]

Oops Sorry,
 
International dialing from US would be 9011T
 
dial-peer voice xxx pots
destination-pattern 9011T
prefix 011
port 0/0/0:23

There is no need for direct-inward-dial on all the dial-peers but dp 1 pots.
 
You need to put forward-digit 7 on dp 100 for local calls to succeed. Likewise on dp 101.
 
Perhaps you need international dialing:
 
dial-peer voice xxx pots
destination-pattern 900T
prefix 00
port 0/0/0:23

[1-79] is going to cause problems with your other dial peers.  If you
do digit by digit dialing (fxs ports, srst/cme phones) then you're
going to hit dial peer 10 for 4 digit numbers that start with 9.

Additionally, since 10 is the only dial peer that will match [0-8]...
there is no reason to have a preference command.

Other than that, it looks alright.  Having incoming called-number . on
all the pots dial peers other than 1 is redundant.  All incoming TDM
calls are going to match the first dial peer in the router with
incoming called-number . (even FXS which can get you in trouble).
It's not going to cause problems but is a misunderstood aspect of dial
peer matching.

As an aside, I prefer to put () around explicit matches that I want to
forward.  For example, destination-pattern 9911 with a prefix of 911
could be simplified to a destination-pattern of 9(911).  The
parenthesis are a regular express non-literal match so they aren't
discarded.  To each his own however.
