2 Special Notes
This section describes limitations and special considerations when using the Synapse
SB67070 SIP Gateway with the IP Flexible Reach Service.
2.1 Emergency 911/E911 Services Limitations and Restrictions
Although AT&T provides 911/E911 calling capabilities, AT&T does not warrant or represent
that the equipment and software (e.g., IP PBX) reviewed in this customer configuration
guide will properly operate with AT&T IP Flexible Reach to complete 911/E911 calls;
therefore, it is the Customer’s responsibility to ensure proper operation with its
equipment/software vendor.
While AT&T IP Flexible Reach services support E911/911 calling capabilities under certain
Calling Plans, there are circumstances when that E911/911 service may not be available, as
stated in the Service Guide for AT&T IP Flexible Reach found at
http://new.serviceguide.att.com . Such circumstances include, but are not limited to,
relocation of the end user’s CPE, use of a non-native or virtual telephone number, failure in
the broadband connection, loss of electrical power, and delays that may occur in updating
the Customer’s location in the automatic location information database. Please review the
AT&T IP Flexible Reach Service Guide in detail to understand the limitations and restrictions.
NOTE: N11 (including 911) calls are not supported unless AT&T IP Flexible Reach Local
Service is ordered!!!
2.2 Special Notes/Unsupported SIP Features
 Passing Calling Number marked private
 T.38 Fax and Super G3 fax machines
 SIP Diversion information. Call forwarding is supported within the Synapse PBX. Caller
ID information for the forwarded call is not retained. The caller does not receive an
indication that the call was forwarded.
 Transferred calls will be looped through the Synapse IP PBX for the duration of the call
and will occupy two trunks. Synapse does not use SIP REFER to handle transferred
calls.
