[asterisk-r2] Calls dropped by asterisk with R2 Telmex

[blackgecko]

Hi guys:

 I have an elastix PBX using a Sangoma a101 pci card to connect a fractional
E1 with TELMEX in Queretaro, the problem is that the calls get hanged up
real quick with no aparent reason at all.when theres only one call it works
all rigth, but when theres more the other calls get dropped.

heres my config

#Dahdi Channels Configurations
#For detailed Dahdi options, view /etc/dahdi/system.conf.bak
loadzone=us
defaultzone=us

#Sangoma A101 port 1 [slot:0 bus:3 span:1] <wanpipe1>
span=1,1,0,cas,hdb3
cas=1-15:1101
cas=17-31:1101
dchan =16

mfcr2_allow_collect_calls=no

Heres a call file of a dropped call, hope you can help me to solve this
issue
