  • 1.  Hotline for IP Telephones

    Posted 04-11-2020 04:53 PM
    Wondering if anyone can help out with this.  We currently have a group of traders that use Auto Ring Down Circuits.  Each of these terminate to CO ports and are assigned an incoming destination extension.  That extension gets created as a 2500 set and the hot line section is setup with the abbreviated-dial system list.  That analog extension is then abrdg'd to the trader phones.  When the press that appearance the call rings their far end counter party.  We are converting these traders to J169 SIP phones and abrdg are not supported via SIP.  We enabled the Special Application SA8887 (Hotline for IP Telephones).  The fields for hotline that are on the analog station now appear when creating the extension as IP.  After adding in the hotline information we then brdged the extension on the trader phone (instead of abrdg).  However, when pressing the appearance nothing happens other than just getting dialtone.  It doesn't follow the hotline info and auto dial the far end.  To validate this I reverted this back to an analog station and abrdg appearance and it works instantly.  Are there any other settings I need to adjust to get this working with an IP station?

    Hi Richard,
    The way Avaya words the description of SA8887 makes me doubt your configuration will work for two reasons:
    1. it says it works when the IP-Station goes off hook.
    2. It says that it doesn't work for SIP phones
    Why can't an autodial button serve? Is there a requirement that the call be placed from an extension that is not the agent's phone? or on a specific secure trunk line?

    For Reference:

    SA8887 - Hotline for IP Telephones
    With the SA8887-Hotline for IP telephones feature, IP stations can automatically place a call to a
    predetermined number inside or outside the PBX when the IP station goes off -hook. This
    predetermined number is stored in Communication Manager as part of the abbreviated dialing
    list. Unless prompted for authorization, the hotline user receives calls normally. The term Hotline
    22 Avaya Aura® Communication Manager Special Application Features August 2015
    Station refers to the IP station configured with the hotline feature. The term Hotline Destination is
    the predetermined number. In Communication Manager Release 6.2 and later, the SA8887-
    Hotline for IP Telephones feature supports overlapped signaling on QSIG trunk.
    Note: The Hotline feature does not work for SIP endpoints.

    This function is utilized on our trade desks to call back and forth across ring down lines to far end brokers.  Morgan Stanley broker goes off hook on his Blackstone line and it rings the incoming destination extension on our end of the trunk.  Not a problem whether these are IP or analog stations.  It's the reverse that's the issue.  Blackstone goes off hook on that same line and if it's analog, it rings straight through to the other side.  Using the SA887 and this becoming an IP/brdg-appr, the behavior isn't the same.  You go off hook and you just get standard dialtone.  What's interesting is if you actually physically log the brdg'd extension in, it does the whole hotline function as expected from the call-appr.  Not off a brdg, which doesn't solve our issue.  

    The only way to work around that is to have 2 buttons for every far end bank.  One for outbound where you can have an autodial of the TG TAC and one for inbound that comes in via the destination extension on the TG.  These folks have about 20+ of these lines and to then double it... 3 sidecars with almost no real estate left. 

    Using h.323/SIP dual registration we have plenty of phones working with brdg-appr on the SIP phones.  I didn't get a chance to see if the hotline would have been honored when going off hook on the bridge because it didn't work via h.323 either.

    We had this exact same question for Avaya recently.  Still no support for the "hotline destination" on SIP phones.  I suggest you open a Feature Request (unless I already did, can't remember).
