[Asterisk-Users] DTMF relay

[Alex Zeffertt]

Hi,

I've noticed that asterisk seems to stop relaying DTMFs after a call has
been up for a while (~10 mins).  I was just wondering whether this was
intentional, or a bug.

In detail here's my setup

	 SIP Gateway --> Asterisk --> E1 --> Asterisk --> SIP Gateway

The LHS gateway sends RFC2833 DTMF messages to the first Asterisk which
bridges them onto the E1.  They then get bridged by the 2nd Asterisk
back to RFC2833 DTMF messages and a tone is heard at the far end.  After
the call has been up a while this stops working.  Strangely, this
problem doesn't occur if you take out the E1 in the middle, i.e. with
this setup

	SIP Gateway --> Asterisk --> SIP Gateway

Like I said - does anyone know if this is intentional...
