asterisk users - Oct 2003 - Caller-ID Spill

Hi All

I am having a warning message appear in my asterisk console when I try
to call from a SIP phone to an analogue phone on my TDM400P.

[12232768320] file chan_zap.c, line 2886 (zt_handle_event): Didn't
finish caller-ID Spill. Cancelling.

I have done some searching of the mailing list but could not find a
resolution.

Any pointers greatly appreciated.

Mark
