Summary:                    [patch] !! Unknown IE 50 (cs5, Unknown Information
Element) & RTCP SR transmission error, rtcp halted
Description: 
Hi,

we have a customer running asterisk 1.4.21.2, zaptel 1.4.11, libpri 1.4.7.
They are using a Digium TE 121 card.

There are about 100 users working on this system. And the system is quite
busy there are about 20 calls concurrent (min).

Everything seems to run fine but when I connect via asterisk -r

I get tons of this message (one every few seconds):

RTCP SR transmission error, rtcp halted
RTCP SR transmission error, rtcp halted
RTCP SR transmission error, rtcp halted

and I get tons of this message (one every few minutes):

! Unknown IE 50 (cs5, Unknown Information Element)

the cusomer is a bit conserned about these two error messages.

what are these two messages about and what should i do to get rid of
them?

please help me.
best regards florian
