[asterisk-users] Forcing Marker bit, because SSRC has changed

[Giorgio Incantalupo]

Hi,
I'm getting a lot of messages like this:

Forcing Marker bit, because SSRC has changed

I searched on internet but found nothing useful.
I have an A102 beronet card on an Asterisk 1.2.9.1 box.
What does that message mean? Is it connected to a problem with the PRI 
line (fastweb italia) or some zaptel/zapata misconfiguration?

TIA
