[Asterisk-Users] MFC/R2 Mexico Unicall Blocked

[Ariel Molina R.]

I've been trying to configure an E1 in Mexico using unicall, i went
into vozdigital, googled this list, and finally followed this
instructions:
http://voip-info.org/tiki-index.php?page=Asterisk+MFC+R2

I have 10 PSTN numbers and 10 "lines" assigned, so i only have 10
"channels" assigned from my telco.

However when i try to simulate a call using this call file:
--------call file------
Channel: UniCall/g1/1
Callerid: <4772140099>
MaxRetries: 0
RetryTime: 600
WaitTime: 600
Context: principal_in
Extension: 014433988789
Priority: 1
----------------------

I get this messages
--------------------------------------
Aug  4 11:46:06 WARNING[9420]: chan_unicall.c:1240 unicall_call:
       Make Call failed - Blocked
Aug  4 11:46:06 NOTICE[9420]: channel.c:1827 __ast_request_and_dial:
       Unable to request channel UniCall/g1/1
    -- Hungup 'UniCall/11-1'
Aug  4 11:46:06 NOTICE[9420]: pbx_spool.c:229 attempt_thread:
       Call failed to go through, reason 0
--------------------------------------

So i can see Unicall channels are configured but blocked (as UC show
channel). There is not much info about unicall so i require your
advice, what can i do? Where do i look?

Also i constantly receive messages
Aug  4 11:54:07 WARNING[9402]: chan_unicall.c:2865 handle_uc_event:
Unicall/14 event Protocol failure

for each one of the 30  (31?) channels.

I send you my configs and important command outputs:
