Hello all. We have an asterisk system set up, and we are seeing a lot of multiple DTMF digits being read by asterisk. In digging through the archives the only answer I have seen is to put in the statement relaxdtmf=yes in the zapata.conf file. Since we are not using any zapata devices, I have tried to put that statement in my sip.conf file to no avail. Any help would be appreciated as my end users are starting to get highly annoyed.

J.If you are using G711 ALAW/ULAW as your codec and you have the DTMF set to sip info or RFC it is possible that the hardware you are using is duplicating it on the audio channel and that asterisk is decoding this. This will result in the data arriving twice, once via sound the other via sip. I cant remember any specific solutions, but I think the grandstream needs to have its DTMF set to sip info to prevent extra DTMF happening. There was a bit on this in here a long time ago so have another trawl through the archives. Good luck Chris
I'm assuming you're referring to the Cisco 7940/7960 phones based on your subject. I'm using G.711u with these phones and have not experienced this problem. My configuration: In sip.conf (Asterisk), I have: dtmfmode=inband for each of the phones My Cisco 7940/7960 config (in SIPDefault.cnf), I have: dtmf_inband: "1" dtmf_outofband: "none" dtmf_db_level: "3" dtmf_avt_payload: "101" I hope that helps. -Shaun ----- Original Message ----- From: B.
