Corporate Directory not showing up

[deadtir3d]

Hi All, we have our main office in L.A. and a remote office in NY running the cisco voip system. A user pointed out what was odd to me, when a user makes an internal call from LA to NY, the full name and number is displayed, when a user from NY calls LA, all we see here is their 4 digit extension. Also, no one from the NY office shows up in the corporate directory in wither office. Is this a CCM, CME or unity issue? Possibly a configuration issue with the switch in NY?

Thanks for any info
Jay
