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!
DAE YEUNG UM
