I have not seen any solutions offered so going to suggest 2:<br>
<br>
1. use an MGCP gateway with 2xT1-PRI and a crossover cable. Add one of
the PRI's in the RG or in a 2nd RG with the SIP trunk. This works well
but it limits to 23 calls (24 if you use CAS) and it costs $$ for the
hardware.<br>
<br>
2. create an h323 gateway that points to the ipaddress of the local
cm. add this to the RG or in a 2nd RG. This is the same approach as
above only use h323 so the hairpin happens in IP. This generally
"works" however it is not well supported. We have identified leaks
associated with this call flow. It is not a typically recommended
config so limitations will not be fixed. All that said, it's adequate
when push comes to shove or possibly enough to get you through an
outage window on other equipment.<br>

<div>Hi, </div>
<div> </div>
<div>I have to integrate a 3rd party IVR system with my CUCM7 via a
SIP Trunk. This IVR will front the entire contact centre which is also
3rd party (dont ask!!). Although these systems appear to integrate ok
I'm a little concerned that I wont have an automatic process of routing
calls and bypassing the IVR SIP trunk directly to the contact centre if
the IVR server experienced an outage. </div>
<div> </div>
<div>If I'm routing the calls to the SIP trunk via a route pattern
the only options I can see are route lists/groups. The contact centre
entry points are CTI Route Points which I cannot insert into the route
list/groups. </div>
<div> </div>
<div>Does anyone have any ideas how I can provide resilliency or am I
better off creating a seperate partition with the contact centre/IVR
numbers and manually inserting that into the ISDN gateway's inbound CSS
during an IVR outage?</div>
<div> </div>
<div>Any help would be highly appreciated.</div>
<div> </div>
<div>Thanks</div>
