[Bristuff-users] Outbound dialing problem

[Redmond, David R]

Hi Michael,

Thanks for the quick reply.  Changing the /etc/zaptel.conf has allowed
me to dial a number from the Asterisk console.  I will be in the office
tomorrow to confirm how the dialing behaves from a handset.

Thanks very much!

Cheers,
David

As far as I know, Japan uses G.711 u-law, not A-law. Which seems to fit
the answer of your telco:

Also that incoming calls do work points in that direction (because the
G.711 law is taken from the incoming SETUP).

To fix this, try to set the b-channels to u-law in /etc/zaptel.conf:
        bchan=1,2
        mulaw=1,2
        dchan=3
        
Not sure if this helps, it might be necessary to change the default law
in the zaphfc/zaphfc.c source.
