[nsp] Bad Bearercap: AS5300 to DEX-600E ISDN

The problem "more than likely" is that you are sending out the Calling
Party# parameter list with the Type and Plan set to unknown/unknown instead
of ISDN and National.... and by YOU I mean.. the Cisco 5300/5400.
Some mobile carriers handle this, some don't (hence the apparent weirdness).
We found on our 5400, we had to use voice translation rules to set these (we
also have other outstanding Cisco issues to do with privacy on the same
deal... more on that later).
Here is a sample config:
! This bit sets those params to National and ISDN
voice translation-rule 50
rule 1 // // type any national plan any isdn
! Now we create the equivalent of a "voice" route-map
voice translation-profile CPN_RDN
translate calling 50
translate redirect-called 50
! Now we apply the sucker to a dial-peer
dial-peer voice 12960 pots
description To Support Trunk Group 1296/1297
translation-profile outgoing CPN_RDN
Best of luck, and I hope this helps... if anything it MIGHT give you lead
with which to talk to the TAC... they weren't much help with us, but our 5E
dudes were instrumental in explaining to the TAC how Q.931 works in the
