32K bytes of non-volatile configuration memory.
32768K bytes of processor board System flash (Read/Write)

Configuration register is 0x2102
==================================================================
it has a VIC 2BRI-ISDN interface  (NT/TE)
which connects to the PBX which is
a Bosch  Tenovis Integral 33EW2 EuroISDN.
We use already another similar cisco at another
office via a WAN link to transfer data and voice
channels between the two PBX's (same).
I made some changes to experiment with
SIP as the hardware already exists.

I somewhere red that my version of Cisco IOS
cannot handle the INVITE command according
to RFC's.

You can see a previous mail with the same
header which has the configuration
and the SIP transaction.

I have already got the 12.3(9)
and I will flash it in the first occasion
and see if it corrects. In the meantime
by playing a line of a small audio
like transfer, does the trick and fools
the cisco and works correctly.

Thanks, and if you got any clues
by my configs I would greatly
appreciate it.
