Hello,

Per the requirements of SIPCONNECT,
I need to support the following behavior in sipx for dialing emergency
services.
How can I determine that the outbound call to the ITSP is an emergency call
based upon the INVITE sent to sipxbridge from the sipx proxy server?

Thanks

'To:' Field
Emergency Services Destinations
The PBX SHOULD format the 'To:' field as follows when an emergency
services call is made:
To: sip:[Country-specific emergency services address];phone-context=
[Predetermined Geographic E.164 addre...@[service Provider Domain
Name] ;user=phone
The country-specific emergency services address is defined as the dial
string used in the country of origin to request emergency services. The
phone-context parameter SHOULD contain a valid E.164 address
previously agreed upon by the Enterprise and Service Provider to
represent the physical location from which the call originated. The
Service Provider SHOULD ensure that valid location information for this
E.164 address is provisioned in the ALI database.
For example, an emergency services call originating in the United
States with a Geographic E.164 address of +16789901234 would be
formatted as follows:
To: sip:911;phone-
[email protected];user=phone
