I have an IP 406 with 12 analog trunks that were just converted from loop start (with caller id) to ground start. Since the conversion I have lost inbound caller id. The provider was able to prove that they are sending caller-id from the CO by connecting a caller-id analog set directly on the trunk at the RJ. The IP office will not display caller ID.

Does anyone have any idea what happened or have any suggestions?

I assume that IP Office supports CID on ground start trunks... am I wrong?

The trunks are delivered from the carrier via a T1 and are converted to ground start analog trunks via an Adtran unit at the customers site. Everything works fine when the trunks are optioned as loop-start.

I understand the IP office required two rings to detect caller-id, and this is not the issue.

What kind of trunk module are they going in to? The ATM4u will not work with ground start. The 16 trunk module, will do groundstart though.
