Fri Oct 16 08:54:47 PDT 2009

Yes, it is what I need. But now I have problem with sending dtmf. Here what
I've done:
[root at centos4-4-vm ~]# telnet localhost 8021
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).

Here I had started to hear A and B. Here what I saw in FS log:

But both A and B couldn't hear me. 
Btw, after I had send dtmf "1" manually from my phone. B started to hear me.
There was this record in log:
2009-10-18 03:47:55 [DEBUG] switch_rtp.c:1767 switch_rtp_dequeue_dtmf() RTP
RECV DTMF 1:2240

Does anybody know, what had I done wrong?

Thanks, Nikita
