[asterisk-users] Help with MFC/R2

[Dae Yeung Um]

Hello 

 

I'm new in this list, but I have some experience working with asterisk and
we are located in Bogota, Colombia.

 

At now I'm having some problems configuring an E1 MFC/R2.

 

 

I have configured Unicall as indicated using the following versions, and
everything "seems" to be correct, but I can't place or receive the calls
(receive CHANUNAVAIL message)

             

asterisk-1.4.21.2     

             libsupertone-0.0.2  

             spandsp-0.0.5       

             chan-unicall-1.4-r01  

             libunicall-0.0.6    

             libmfcr2-0.0.6        

             zaptel-1.4.11

 

Inside asterisk, I can see the all UC channels active and Idle:

 

             asterisk*CLI> UC show channels

             Channel Extension  Context         Status     Language
MusicOnHold

                   9            from-pstn       Idle       en
default

                  10            from-pstn       Idle       en
default

                  11            from-pstn       Idle       en
default

             (omitted)

                  34            from-pstn       Idle       en
default

                  35            from-pstn       Idle       en
default

                  36            from-pstn       Idle       en
default

                  37            from-pstn       Idle       en
default

                  38            from-pstn       Idle       en
default

                  39            from-pstn       Idle       en
default

 

 

 

I configured the testcall.conf to check:

 

             destination-no 6055151

             protocol-class mfcr2

             protocol-variant ar,20,4

             protocol-end cpe

             on-offered accept

             circuits 9-10

 

 

 

But the system answer with:

 

             # ./testcall

             Chan 9, class 'mfcr2', variant 'ar,20,4', end 1, caller 0, from
'' to '6055151'

             Chan 10, class 'mfcr2', variant 'ar,20,4', end 1, caller 0,
from '' to '6055152'

             Loading protocol mfcr2

             Failed to open channel: Device or resource busy

 

 

 

 

Anyone has any Idea why I can't place or receive a call?

 

 

Your help will be really appreciated!
