[Asterisk-Users] R2 implementation problem

[Manuel Marin Garcia]

I have a TE110P connected to a Telmex E1 circuit with R2 signaling.

Asterisk version= 1.0.10
Zaptel= 1.0.1
Spandsp=0.0.3pre6
Unicall= 0.0.3pre8

*zaptel.conf
span=1,1,0,cas,hdb3
cas=1-15:1101
cas=17-31:1101
dchan=16
loadzone = us
defaultzone=us

*unicall.conf
immediate=no
loglevel=255
protocolclass=mfcr2
protocolvariant=mx,10,4
protocolend=cpe
group = 1
context = telmex
channel => 1-15
channel => 17-31
*
*chan_unicall is compiled without any problems and when asterisk starts 
I see all channels in idle state. The problem is that I am unable to 
make or receive calls. When there is an incoming call I see the following

Incoming Call (I receive 10 ANI digits and 4 DNIS digits) I suppose to 
receive 0875 for DNIS

There is a 9 or 10 seconds pause and the I receive the following

*NOTE*:
I Already tried changing values for DNIS and ANIS and same problem
I tried with other versions of spandsp and unicall and same problem
The same occurs in Asterisk version 1.2.3

Does someone has experience configuring R2 in TE110P boards?


Any ideas or suggestions will be appreciated


Thanks
