asterisk users - Sep 2004 - I forgot to add my email please contact me offline we have around 300, 000 to 1/2 million minutes per month for India and Pakistan .. can ztdummy help trunk mode?

Hi all, did not find much info in lists about subj.
I have ztdummy working properly because I can use conferences without
any errors.
But when I try to use trunk=yes, I get the following:

Sep  2 21:20:51 WARNING[1137720112]: chan_iax2.c:6422 build_user:
Unable to support trunking on user home' without zaptel timing
Sep  2 21:20:51 WARNING[1137720112]: chan_iax2.c:6246 build_peer:
Unable to support trunking on peer 'home' without zaptel timing

Can something be done??

Thx in advance for your replies.
