Asterisk does not detect dtmf signals of some subscribers from pri. I see this problem in Asterisk. I have cisco 5350 which normal detect signals from the problem (for Asterisk) subscribers from pri.
What do ?
Are you using a Digium card to terminate that PRI?
You can use pri debug to see more. Make sure 5350 can send dtmf…
hi:
what the hardware and software environments? show the debug info, please.
I have a digium te220b card … and I had a dtmf problems tooo … and problem was with echo canceler … that canceled some of dtmf signals too 
IF you have echo canceler … tray to turn it off
yes, Wildcard TE210P (4th Gen)
no, i tried to use instead of Asterisk the 5350 and everything worked.
My schema :
Other PBX -pri- Asterisk PBX , from SOME subscribers of the “Other PBX” dtmf don’t work
but if :
Other PBX -pri- Cisco 5350 , dtmf always work
[quote=“james.zhu”]show the debug info[/quote]In logs about dtmf nothing (from problem subscribers), because Asterisk does not detect the dtmf.
[quote=“angel.inc”]IF you have echo canceler … tray to turn it off[/quote]yes, i am using mg2… will try use oslec.
