  • Tie Line between Cisco and ShoreTel

    Question:

    One of our customer is currently running Cisco VoIP and they just opened a new office for 100+ users and they want ShoreTel for that office.

    Can I Tie Line the Cisco office to the new ShoreTel office?

    They just want to be able to dial ext between offices....

    Network between offices could be Point to Point or MPLS.


    Any suggestions would be great.


    Thanks,
    Pete

          This is not uncommon. The easiest way to tie them together is via a ShoreGear T1 (or T1K) connected to a Cisco T1 interface. The main decision is whether you put the ShoreGear T1 at that remote site and use a point to point T1 line or put it next to the "core" Cisco switch across the MPLS from the remote site.

          After that it's just a matter of adding the list of "Off System Extensions" on both the Cisco and ShoreWare Director

            This is very easy. You can configure a trunk with Off System Extensions on the ShoreTel side. You'd either need to use a PRI (which requires a SG-T1/T1k/220T1 switch), or you can use SIP trunking (which requires licensing).

            PRIs are simpler, but SIP trunking offers more flexibility in physical placement (since it can connect anywhere so long as it has network access, instead of requiring a dedicated physical line).

              Hi Alex,

              I am in a similiar situation, I am currently testing a SIP trunk from a shoretel (remote and users are pointed to the sip trunk) to a switchvox (HQ with all the PSTN) environment. NORMAL calls are OK, but I am getting dodgy results on "transfer" and "conference". conference button on the shoretel phones DO NOT WORK at all, once i hit the conference, the switchvox MOH kicks in and the first caller gets put on hold indefinately and never joins the call.

              Transfer works most of the time, but recently, my transfer button became a "conference", when I try to transfer a call, all parties get put in a conference.

              So in my opinion, DO NOT DEPLOY SIP Trunks with shoretel, would advise to use only E1 pri or T1 Pri Tie trunks.

              Shoretel 12.1 GA
