BCM shows anonymous as CID

[SCs5thGen]

I believe it all started when we changed from H323 to SIP sttings on VOIP trunks. The incomming CID from outside works fine, it is only on VOIP calls. CID shows the ext calling from some BCM 50s but anonymous from some other BCM 50s in our network. Anonymous is shown on the BCM 400 4.0.
We also have an Asterisk Box that gets the CID(ext number) from all the BCM 50s but anonymous from the BCM 400. BCM 50s are at 2.0 and 3.0

Any ideas?

Do you have the MCDN license in the Bcm400?

I do not have the MCDN keycode and never have, but this used to work... Also this is between all BCMs, no Meridians. My understanding is that I do not have to have it unless I have an Option - PBX in the mix.

You could have mcdn license in a Bcm's network only, it makes it easier to program(only one target line instead of two if you have did's),allow CLID between Bcm's, allow TAT which makes a better use of your VoIP trunks,etc...

We have similar problem with BCM 450 R1.
External IVR is connected to BCM 450 with trunk lines (SIP or PRI)and we can see CID on that IVR when external call comes on DID.
But when we receive external call and it goes via Auto Attendant then we dont see calller ID on these trunk lines.
On the PRI we were using NI2 and instead of external caller ID we were seeing BCM extension number.

Do we need to use MCDN?
