Alarm 63

[bostech]

I have a customer that occasionally gets an Alarm 63: No DTMF Receivers Available.

They have the following:

BCM400 4.0 w/ Expansion Cabinet
1 - DTM
1 - GATM4
4 - GASM8
2 - DSM32+
4 - IP Trunks (Used for multi-site company)

I know that there are a limited number of receivers, but does anyone know what the maximum # of receivers there are?

Thanks.
