Hi , I have an asterix (1.2.7.1 <http://1.2.7.1>) box with 3 TDM400P and 10 FXO modules, and zaptel (1.2.5). The problem is that 6 modules can't be initaized and i get the folowing error: May 7 09:17:37 WARNING[7739] chan_zap.c: Unable to specify channel 9: No such device May 7 09:17:37 ERROR[7739] chan_zap.c: Unable to open channel 9: No such device
here = 0, tmp->channel = 9, channel = 9

In general terms, the problem seems to be related to exactly which TDM card is considered first, second, and third. The order in which they are used is not necessarily related to which pci slot they are located in. (Just went through the same issue yesterday.)

Since channel 9 is the one causing the issue, it is the TDM card with only two fxo modules on it. The other two cards are channels 1-4 and 5-8.

ztcfg output is:

Zaptel Configuration
======================


Channel map:

Channel 03: FXS Kewlstart (Default) (Slaves: 03)
Channel 04: FXS Kewlstart (Default) (Slaves: 04)
Channel 05: FXS Kewlstart (Default) (Slaves: 05)
Channel 06: FXS Kewlstart (Default) (Slaves: 06)
Channel 07: FXS Kewlstart (Default) (Slaves: 07)
Channel 08: FXS Kewlstart (Default) (Slaves: 08)
Channel 09: FXS Kewlstart (Default) (Slaves: 09)
Channel 10: FXS Kewlstart (Default) (Slaves: 10)
Channel 11: FXS Kewlstart (Default) (Slaves: 11)
Channel 12: FXS Kewlstart (Default) (Slaves: 12)

10 channels configured.

The above is only reflective of what you define in /etc/zaptel.conf. If those definitions are incorrect (eg, incorrect order), you will see the above display. Since you already know channel 9 does not have a module in it, the zaptel.conf should probably read something like:

fxsks=1-8,11-12

After correcting the above, you'll need to change zapata.conf to exactly match the entries in zaptel.conf.
