E911 in a SIP mastered network

My boss wants me to setup a VoIP network where the connection to the PSTN would be either over a channelized T-1 or a PRI. He also wants me to do this using SIP instead of Call Manager. My questions is, how would E911 would in the enviroment?

Thanks

Mike

Re: E911 in a SIP mastered network

This draft on SIP dated Nov2002 http://www.sipcenter.com/files/Mitel_SIP_Enterprise.pdf talks about E911 support on SIP and says it not yet standardised as on that date.

You may want to verify it though before you go ahead with this solution.

The only solution that I am aware of for E911 is the Cisco's Emergency Responder(ER) based on Call Manager. More details on ER here ---> http://www.cisco.com/en/US/products/sw/voicesw/ps842/index.html

You can try this to see if it will work with your local telco.

Assign the DID to the end user in the local telco db or you can use feature set D if the local telco will support it. With feature set d upon call setup enduser details are sent with called/calling information. Both of the above are not supported in E911 but are a workaround for the expense psap line required by most E911 services.
