2 Public Addresses for PSTN SIP Trunk ob BE4K?

[johnsnave1]

Hi,

I have a question from a end user who is thinking of migrating their existing telephony from CME to a BE4000 and moving from Primary rate ISDN to a SIP trunk to the PSTN:

Is it possible to configure two public IP addresses on the BE4000 ? It seems possible on the 3000 and 6000?

What are you trying to accomplish? You mean 2 destination IP addresses to a SIP Trunk so as to achieve redundancy?

[johnsnave1]

Exactly so- for redundancy.

[Georgios Fotiadis · Accepted solution]

Yes, that you can do. You can add multiple destinations to the SIP trunk configuration.

Though, I would suggest using a CUBE and not have your CUCM directly access the ITSP through public IP addresses; for the sake of security.

Many thanks for your very prompt reply.
