I'm having an interesting issue with my Call Manager and CER. When a user dials an outside line, the route filter we have set up sends them to a 9.@ route pattern. However, with our CER configuration for PSAP callback, there is also a directory number 913XXXXXXXXXX configured on a CTI route point for ELIN identification.
So, when a user dials a 9.13XXXXXXXXX, the call manager waits to route the dialed number as there could possibly be an extra digit. Therefore, a user must wait for the t302 timer to timeout when dialing any area code that begins with a 3.
Is there any way to fix this besides lowering the T302 timeout to keep the end-user from becoming frustrated, or re-doing our whole route plan away from route filters and 9.@ route patterns?
