Summary:                    BRI Span goind down - Unable to receive TEI from
network in state 2(Assign awaiting TEI)!
Description: 
After upgrading dahdi, libpri and Asterisk to to most recent SVN versions
there seem to be an issue causing a span to go down after several calls.
Libpri (chan_dahdi) does not seem to release calls properly because of
protocol timer issues on the BRI interface.

Versions used:
- Asterisk SVN-branch-1.8-r284281 (Problem also occours with 1.6 trunk)
- DAHDI SVN-trunk-r9205 with MG2 echo canceller
- LibPRI SVN-branch-1.4-r1929

Errors seen on console (debugging disabled):
[Aug 31 12:44:52] ERROR[11003]: chan_dahdi.c:13534 dahdi_pri_error: 4
Unable to receive TEI from network in state 2(Assign awaiting TEI)!
[Aug 31 12:44:52] ERROR[11002]: chan_dahdi.c:13534 dahdi_pri_error: 3
