Re: [hylafax-users] lastDialFailure:"No carrier detected" - Asterisk + Hylafax via IAXModem

[Duncan Turnbull <duncan@xxxxxxxxxxxxxx>]

Hi Pimjai

I had this skew adjustment before too but it didn't come every time -  
Lee could explain further and its worth checking the iaxmodem forums  
but I think the key bit is the remote hangup message

The Unknown DSP control handler: 8 is just a message according to Lee  
and I get it a lot and it doesn't seem to matter

The bit is despite all the errors etc is that the sending fax hung up  
first and its most probably because it can't hear the carrier signal  
- this is reflected in the NO CARRIER message from hylafax.

Dial it from  another phone and listen to how loud it is, you can  
play with the sound levels in Asterix but this is not so much  
anything to do with hylafax as the telephony network

Check out Zapata.conf which has tx and rx levels - if you are using  
analog lines (not sure if applies to ISDN) and find and use the  
ztmonitor  tool to get a view of the noise levels It sounds like you  
need to boost the transmit so the far end hears better but you may  
also need to bump up the receive for your iaxmodem to hear the far  
end and then respond. Its a bit of trial and error unless you have  
proper sound gear

Cheers Duncan
