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

libpri_ie50_cs5-trunk.diff2.txt:
Since code set 5 is national specific, the standards documents really need
to be referenced for verification and understanding.

The cpc2str() takes an integer and will supply a string from it's table
when a value 0-15 is supplied.  It is only called where it is given a value
of 0-7.  Incorrect decode is very likely because of the mismatch in field
sizes expected.
