[Linphone-developers] DTMF issue

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?
