asterisk users - Jun 2005 - Unable to support trunking .... without zaptel timing

When I start Asterisk, I receive these errors:

Jun 13 16:26:05 WARNING[2870] chan_iax2.c: Unable to support trunking on
user 'gv_trunk' without zaptel timing
Jun 13 16:26:05 WARNING[2870] chan_iax2.c: Unable to support trunking on
peer 'gv_trunk' without zaptel timing
Jun 13 16:26:05 WARNING[2870] chan_iax2.c: Unable to support trunking on
user 'zoom_trunk' without zaptel timing
Jun 13 16:26:05 WARNING[2870] chan_iax2.c: Unable to support trunking on
peer 'zoom_trunk' without zaptel timing

I have a TE110P card and IAX setup between two servers that appear to work
fine. The only reason this has come to my attention is when I was trouble
shooting an error with our Mitle SX200 that was reporting:

T1/BRI Card at 02 06 00 00
Has exceeded the maint loss frame threshold.

My main question is in regards to the timing error but if anyone has any
Mitel experience (scott w!) that has seen this other error.= I'd be happy to
hear about it....
