Special Notes

Emergency 911/E911 Services Limitations

While AT&T IP Flexible Reach services support E911/911 calling capabilities in certain

circumstances, there are significant limitations on how these capabilities are delivered.

Please review the “AT&T IP Flexible Reach” Service Guide in detail to understand these

limitations and restrictions.

BCM Soft Phones not currently supported

Avaya BCM soft phones are not currently supported with the AT&T IP Flexible Reach

Services.

Ring back Issues with Unattended Transfers

An unattended transfer is one in which the party initiating the transfer hangs up prior to

answer by the party to whom the call is being transferred. When 2 phones are in an

active call on the BCM and one of those phones performs an unattended transfer to

certain endpoints on the AT&T network, the BCM phone remaining on the call will not

hear ring back prior to answer.

T.38 Fax must be used

T.38 fax should be configured on the BCM with AT&T IP Flexible Reach service. Fax via

G.711 transport should not be used on the BCM.

Error Correction Mode Not Supported

In T.38 fax calls originated by the BCM, during capabilities negotiation, BCM disables

Error Correction Mode (ECM); therefore, these particular calls will not use ECM during

fax transmission. However, calls will still work.

Find Me/Follow Me Restrictions

Directory Information (i.e., 411 and 555-1212) and 8YY numbers should not be used for

Find Me/Follow Me external destinations.

20-byte G.729 Payload Size to/from PSTN

The G.729 payload size will always be 20 bytes with calls to/from PSTN.

G.726 Codec not supported

BCM does not support the G.726 codec – G.711 and G.729 codecs should be used.
