[asterisk-users] Can't make call with TDM410P

[neo haux]

Actually I can start and receive SIP calls (PC client, iphone client)
but I have an issue with calling external number throught PSTN
(certified-asterisk-1.8.11-cert2).

I'm having this  error when making a call:

*CLI>   == Using SIP RTP CoS mark 5
    -- Executing [9000 at local:1] Dial("SIP/3000-00000006",
