E1 R2 Category

[Leonardo Santana]

Hello,

Can someone explain what is the E1 R2 category?

Specifies the type of call (subscriber with priority or normal subscriber). ITU default is 1 (normal subscriber). For outgoing calls, the router sends this category. If this is not configured, the router sends the country default category. For incoming calls, the router collects the category from the switch. No special handling is based on the category.

E1 R2 is variant of E1 CAS circuit, most often seen in Latin America countries in my experience. You follow typical E1 CAS (not PRI) configuration with R2 settings. You can find many config examples online if you google it.
