The tech director of the voip provider told me that it is not a timing issue and more to do with my config.
Let's not cynical about the way I raised the question. I know there is no matching peer. I do not using windoz myself and I am not accustomed to pop up gui. But why there is no matching peer, this is not expected. I presume ztdummy will provide the same timing device as zaptel card. But apparently it is not. Or is it really due to missing of zaptel card on the other peer.
My iax.conf is as follows: [general] port=5036 bandwidth=low disallow=all ; same as bandwidth=high allow=gsm allow=g729 ;disallow=g723.1 ; Hm... Proprietary, don't use it... disallow=lpc10 ; Icky sound quality... Mr. Roboto. jitterbuffer=yes dropcount=3 maxjitterbuffer=500 maxexccessbuffer=100 trunkfreq=20 ; How frequently to send trunk msgs (in ms) register => iax_home:[EMAIL PROTECTED] trunk=yes tos=lowdelay [iax_office] type=friend #auth=md5 context=int-ext disallow=all allow=g729 trunk=yes
The other thing may be helpful is what modules should be loaded without zaptel card. My lsmod show me:

have I got the necessary modules to do trunking? -- David Kwok Tel: 612 99292086 ext 1002 Iaxtel/FWD # 17001813482 ext 1002
