In global config:

as5348#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
as5348(config)#voice service ( I hit tab here)
as5348(config)#voice service voip
as5348(conf-serv-sip)#exit (Do a ? here to change defaults....)

Later down in the config...

 max-forwards 15
 sip-server ipv4:

The SIP-UA is optional, but it will be the default if it's not specified
in the dial-peer.

VoIP inbound dial-peer's that don't specify a session protocol or
specify SIP will be used for inbound SIP calls.

POTS outbound peers will be used by both SIP and H.323.

What do you exactly mean by "turning on sip". I did define a sip-ua
and left the dial-peers alone at first and then tried with additional
dial-peers from another cisco box which was only serving SIP calls.

The cisco is running:
IOS (tm) 5300 Software (C5300-IS-M), Version 12.2(5)

Its still declining our calls with:
(ips and numbers obfuscated)
Status line: SIP/2.0 500 Internal Server Error

         Server: Cisco VoIP Gateway/ IOS 12.x/ SIP enabled
         CSeq: 101 INVITE
         Content-Length: 0

Is it possible that there must be no h323 config on the ethernet like:
(again obfuscated)

interface ethernet 0/0
  h323-gateway voip interface
  h323-gateway voip id SOMEGK ipaddr a.b.c.d 1718
  h323-gateway voip h323-id DASECRET

I cant remove this definitions because this cisco is in production
and its not ours.

thanx & best regards,
