Port 445

[motorollin]

This is an obscure question, but maybe someone can give me an insight.

We use an AVST CallXPress voicemail server at work, which has a GUI front end for administration. I'm trying to figure out what protocol is being used behind the GUI as I want to write a cut-down GUI for our helpdesk so they can do small admin tasks (like voicemail PIN resets, mailbox name changes etc).

I have run a packet sniffer while logging on to the CallXPress server and it opens connections on port 445. I Googled this port and it seems to relate to NetBIOS over TCP/IP, though I fail to see how this could be used to interface with a voicemail server. I tried telnetting in to the server on that port and it established a connection, but I just got a flashing cursor.

Any ideas what protocol this might actually be using?

Isn't port 445 used for ssl connections?  Could it be using a secure webserver of some sort  ?

Just seen your reply - thanks. I'm not aware of a secure HTTP service on the server but I'll check. The front end is not web-based but I suppose it's feasible that it's using HTTP as the communication protocol.

Cheers
