1 Architecture Proxy, Redirect, Registration server. Authentication Programmable (SIP- CGI) OpenSource SQL database: MySQL http://www.mysql.com User information: Contact location Profile (e.g., password) Aliases Conferences Address book System information Configuration SQL database sipd

2 Architecture Web based configuration Web server User profile can be modified using web browser. Creating new user (admin/normal) Changing profile and contact information (“follow me” service). Web CGI scripts Both sipd and web scripts use the database SQL database sipd

3 Architecture Web based configuration Web server IP phones connected to the departmental LAN. Users are identified by id, e.g., “hgs@cs.columbia.edu” Software (sipc) for desktop. Allows audio, video, chat, white board, device control, instant message, presence and desktop sharing. Also plugnsip. SQL database sipd e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

4 Architecture Web based configuration Web server Phones register themselves with sipd when powered up. Sipd stores the contact information in the database table: hgs@cs.columbia.edu => hgs@128.59.19.233 There can be multiple contacts. All registered phones ring, and the first to pick up is connected. SQL database sipd Regsitration can also be altered from the web interface e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

5 Architecture Web based configuration Web server (2) Phone rings, the user picks up the call and can talk to the caller. (1) When somebody calls hgs@cs.columbia.edu, sipd gets the INVITE message and forwards the call to the current location. Another IP phone Based on user profile, sipd may ask for caller authentication. SQL database sipd e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

6 Architecture Telephone SIP/PSTN Gateway Department PBX Web based configuration Web server Cisco 2600 router with SIP/PSTN gateway connects the departmental LAN with the PBX. Departmental PBX (Nortel Meridian) connects both internal and external lines to the gateway. Telephone switch Internal T1/CAS External T1/CAS (Extension:713x) Dial “8” to reach outside line SQL database sipd e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

7 Architecture Telephone SIP/PSTN Gateway Department PBX Web based configuration Web server (1) When PBX receives a call for 9397134, it forwards the call to extension 7134. 7130-7139 is assigned to the gateway. Telephone switch Internal T1/CAS (Extension:713x) Dials 9397134 128.59.19.141 SQL database sipd (2) The gateway forwards all PSTN calls to sipd; sip:7134@128.59.19.141 (3) Sipd looks into the dialplan, finds a mapping 7132=>wenyu@cs.columbia.edu and forwards the call to the current location of “wenyu”. e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

8 SQL database sipdArchitecture Telephone SIP/PSTN Gateway 128.59.19.28 Department PBX Web based configuration Web server (2) Sipd authenticates the caller and checks permissions. Sipd maps the number 5551212 to 85551212@128.59.19.28, adding the prefix “8” and the gateway address. (3) PBX forwards the call to external line. Telephone switch 128.59.19.141 (1) The IP user dials “sip:5551212@cs.columbia.edu”. Dial “8” to reach outside line External T1/CAS (4) PSTN user receives the call. e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

9 Architecture Telephone SIP/PSTN Gateway Department PBX Web based configuration Web server Can use no-DID (direct inward dialing) mode for more numbers. Telephone number mappings and privileges modifiable from the web Telephone switch Internal T1/CAS External T1/CAS SQL database sipd e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

10 Architecture Telephone SIP/PSTN Gateway Department PBX Web based configuration Web server SNMP agent for SIP MIB. Allows remote monitoring and control of the SIP server. (e.g., prompt when an unauthorized registration is attempted) Telephone switch SNMP (Network Management) SQL database sipd e*phone sipc Software SIP user agents Hardware Internet (SIP) phones

11 Architecture Telephone SIP/PSTN Gateway Department PBX Web based configuration Web server Telephone switch SNMP (Network Management) Allows an H323 client (Netmeeting) to use the services of our SIP infrastructure.
