Hi,
I'm encountering an issue with Linphone DTMF, I tested it with some B numbers with DTMF input and DTMF is working fine, however for some reasons certain B numbers, it' not recognizing the DTMF tones being sent, does anyone have any idea on what's wrong? I have only activated PCMU and PCMA as codecs both 8000Hz. I'm using freeswitch as my SIP server. Does this have to do with RFC2833 and RFC4733?
Thanks,
Jason
