[asterisk-users] Unable to create channel of type 'DAHDI' (cause 0 - Unknown)

[Walter Arguello]

Hi,

I have a tdm22b (2 fxs / 2 fxo)

When Asterisk is just started, outbound calls routing to fxo port, do not working with error:

Unable to create channel of type 'DAHDI' (cause 0 - Unknown)

Inbound calls to fxo port work fine.

After first inbound call, the outbound calls starts working.

CentOS 5.4
asterisk 1.6.0.21-1
dahdi 2.2.1.-1

Can anybody help me to identify what is the possible cause of problem?

Thanks,

Walter.
