CTMS SIP Logs "SIP/2.0 500 Internal Server Error"

Hi TelePresence Guru's

I have noticed the following in the SIP logs of my Cisco TelePresence Multipoint Switch (CTMS) :

SIP/2.0 500 Internal Server Error
Via: SIP/2.0/UDP 192.168.37.70:5060;branch=z9hG4bK2b0f766df9be6
From: <sip:63844@192.168.37.70>;tag=988fbe52-93f3-4aa8-a0cf-cb798ce197d5-42282222
To: <sip:80000@192.168.37.30>;tag=001e0bcca50c05dc5d856652-1d48c79a
Call-ID:
45341e00-c8e12115-4d0eac-4625a8c0@192.168.37.70
Date: Mon, 13 Sep 2010 13:03:17 GMT
CSeq: 102 SUBSCRIBE
Content-Length: 0

As it stands I have not noticed any adverse effect.  Has anyone noticed these in their SIP logs?  Obviously it would be nice to know what 'Internal Server Error' means in this case and whether I should be concerned.

Thanks for reading.

That seems to be coming from a SUBSCRIBE message perhaps coming from KPML/DTMF support,
if no error, its ok,
CTS endpoints and CTMS do not support sending/passing DTMF.  As we
implement more interoperability solutions, we will add it to future roadmap discussions
