[Asterisk-Users] Swissvoice ip20 MGCP issues

Sat Nov 12 13:26:36 MST 2005

Hello there, i have a swissvoice MGCP ip20 as the subject suggests. I 
have it connecting to asterisk and it shows in `mgcp show endpoints`:

*CLI> mgcp show endpoints
Gateway '192.168.0.10' at 192.168.0.10 (Static)
    -- 'aaln/1 at 192.168.0.10 in 'desk-phone' is idle

however when trying to dial '5' (should answer and playback 
hello-world') I get an error tone from the phone and the following 
messages from asterisk:

1. Non-debug:
      -- Message check requested for mailbox /folder INBOX but voicemail 
not loaded.
     -- MGCP mgcp_new(MGCP/aaln/1 at 192.168.0.10-1) created in state: Down
(i then hung up)
     -- MGCP handle_request(aaln/1 at 192.168.0.10-1) ast_channel already 
destroyed, resending DLCX.
     -- MGCP handle_request(aaln/1 at 192.168.0.10) set vmwi(-)

2. Debug:

Does anyone have a clue what is going on? the debugging information 
means little to me.
