4.4.9 Adding a secondary or backup server for call routing & registration

For redundancy purposes, the SP may require a backup registrar server or proxy server

for SIP calls in case the primary server(s) goes down.

4.4.9.1 Adding backup registrar server for SIP registration

For certain scenarios, the provider may have a backup SIP registrar server – below is an

example of adding a backup server with IP address 10.1.100.253.

sip-ua

registrar ipv4:10.1.100.253 secondary

4.4.9.2 Adding backup proxy server for inbound / outbound calls:

This implies duplicating the outbound dial-plan on the UC500 via dial-peers. This is

similar to section 4.4.8 and will not repeat all the config here. The key addition would be

to create new dial-peers (new tags) pointing to the backup proxy server (in the example

below it is 10.1.100.253):

dial-peer voice 12001 voip

corlist outgoing call-local

4.4.10 Registration of Multiple DID numbers with unique credentials

There may be a requirement to register all DID numbers for a UC520 to the SP instead of

the parent – child registration method. This is possible on the UC520 and also allows for

unique credentials (username, password, realm) per DID. Below is an example for this:

sip-ua

registrar ipv4:10.1.100.253

credentials username 4085551201 password 123 realm Cisco.com

credentials username 4085551202 password 456 realm Cisco.com

credentials username 4085551203 password 789 realm Cisco.com
