Just installed 2 PRI's and outbound caller ID is working fine except when I dial a zero. My carrier is saying that when I dial a zero, they are not getting any called party ID and thus cannot complete the call. I've tried direct accessing the trunk group to ensure that there is no weird routing taking place and have the same problem. International calls (011) work fine, as do local or LD with the callers extension being displayed. If I go over a copper trunk instead of the PRI and dial zero it also works OK. The carrier says they are getting some type of "Locking Shift Error" which they think is some Nortel proprietary message. Can't find anything on it and am stumped. Any ideas? Thanks.

Try and turn on messaging for the dchannel. Also check to see how the "0" is built. In most cases this is an SPN. with messaging on (ENL MSGI XX, ENL MSGO XX) it will tell you how the call is being presented to them. It should also tell you why the call is rejected.
