[Asterisk-Users] MGCP Problem.

Hi. 
I'm new in Asterisk with MGCP. I set up a MGCP user agent and start asterisk
with the next configuration files.

'--------------- extensions.conf

[general]
static=yes
writeprotect=yes

[globals]
ap1 => mgcp/aaln/ap200@64.76.148.186

[macro-apl1]

;exten => s,2,Voicemail(u${MACRO_EXTEN})
;exten => s,3,Hangup
;exten => s,102,Voicemail(b${MACRO_EXTEN})
;exten => s,103,Hangup

[SIP]
include => ent

[ent]
exten => 112,1,VoiceMail(b112)
exten => 111,1,Macro(apl1,${ap1})

When i hook off the endpoint i obtain the next debug in the asterisk CLI.

Looks like your phone has been given a name ('ap1'). If your phone
thinks it
is called 'ap1' you should set that name in mgcp.conf too, otherwise it
won't be recognised.

[Asterisk-Users] MGCP Problem.

Hi.  
Thanks for the tip.  Now i'm able to recognize the endpoint MGCP. But i can
not place a call.  I'm attaching the debug from the asterisk and two
configurations files (mgcp.conf and extension.conf).  For my first test i
just want to call the voice mail, that has the 112 extension.  


The debug from the Asterisk when is started.

 [chan_mgcp.so] => (Media Gateway Control Protocol (MGCP))
  == Parsing '/etc/asterisk/mgcp.conf': Found
    -- Allocating subchannel '0' on aaln/0/0@AP200
    -- Allocating subchannel '1' on aaln/0/0@AP200
    -- Added gateway 'AP200'
  == MGCP Listening on 64.76.148.185:2427
  == Using TOS bits 0
  == Registered channel type 'MGCP' (Media Gateway Control Protocol
(MGCP))
    -- MGCP Auditing endpoint aaln/0/0@AP200 for hookstate

Now the debug:

 <<MGCP_Debug.txt>> 

And the configuration files.

 <<mgcp.conf>>  <<extensions.conf>> 


Any ideas?

Thanks in advance.
