I've been having a problem getting DTMF passed through from registered phones to my termination provider. Sometimes it works, sometimes it doesn't. My provider is set for rfc2833.
In looking through the mod_sofia.conf.xml file, and the sofia sources, it appears that the only two options for DTMF are info and rfc2833. I've tried various combinations and the only thing that ever seems to even sometimes work is if pass-rfc2833 is set to true. I've tried this with Linksys SPA 942 phones, Grandstream GXP 2000 phones and Cisco 7940 phones. Doesn't seem to make a difference. I've also tried various dtmf-durations and that didn't seem to have an effect either. However, after doing various searches it appears that not explicitly setting a dtmf-type in a sofia profile, it defaults to using inband DTMF. Is this correct? If inband DTMF is the default, then I will have my termination provider switch my account over to using inband instead of rfc2833. - Marc -- Marc Lewis Avvatel Corporation _______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
