[Freeswitch-users] PRI + FreeTDM problems

Tue Jun 19 04:18:16 MSD 2012

hello all,   i had this problem months ago and didn't really have the solution,just thinking that maybe someone from here can help.

our primary link for calling outside is a PRI.
so here's what we currently have, when we try to call 18778025246 and  1866-642-5246 - calls are not going through.

but when we call 18775682495 - calls go just fine.

attaching my freetdm.conf.xml too as the provider made me change some fields in there.

pasting the logs provided by our PRI provider telepacific.com,with comparisons for both numbers dialed and labelled as good and bad calls,

please take note that 18778025246/1866-642-5246 goes thru our sip provider just fine. no problems at all. not with the PRI.
i pressume both numbers are toll free.

i had help from sangoma support no response yet with the 'called number' issue.

wanrouter version

WANPIPE Release: 3.5.27
 i have updated the libsng_isdn to the newest driver as suggested,

pcap sent to sangoma support is saying that when calls go through, i am NOT specifying a 'called number'
but bad calls are having that 'called number' .

now the problem is i am not really setting anything specific (e.g adding that 'called number' field to specific numbers when called)
