Howto:Config size Limitations

Limitations

There are various global restrictions in the config size:

• the total size of "config change" commands must not exceed 29kB
• the total line length must not exceed 20kB (for v11r2 and earlier versions the limit is 8kB)
• the number of whitespace separated strings (words) on a config line must not exceed 1024

There are some special restrictions in the config size:

• No more than 32 alias entries are allowed on one Gatekeeper/Registrar interface.
• No more than 6 Hardware IDs on a PBX Object are possible.

So if there is a problem, you can try to use shorter aliases, leave out redundant informations. Nevertheless, it is ugly.

Weak Scenarios and alternative Solutions

Many number mappings in the routing engine

Use PBX Features instead:

• E164 Setup
• Howto: external ACD Routepoint logic
• separate Node with CFx's
• Howto:Central_SIP_trunk_with_multiple_subscriber_numbers - uses an additional PBX and GW-interfaces to map subscriber numbers to internal extensions
