I need your help and inputs...I need to add "another country" to our CUBE. Our use case is:
Actually, we are service country A (Switzerland) with a SIP Trunk from SP "ABC". Incoming and outgoing calls are working fine.
Between SP "ABC" and our CUBE, we have a SIP Trunk. On SP side, they have one IP for Signaling and one IP For the RTP Stream. We have one DDI range which is forwarded from CUBE to our CUCM.
Now, I have to add a second country (DDI) and for this, I have to speak with another IP for the Signalisation. RTP IP will be the same.
How do I need to configure the CUBE so that DDI of country A (Switzerland) will use the Signalisation IP A and the DDI of country B (Spain) will use the Signalisation IP B? Please check also my quick and dirty attached diagram.
This kind of design on the WAN side with this dedicated Signalisation IP's is mandatory from our SP.
In the future, we need to add some more countries and this fact I have to consider as well in the configuration.
Some infos about our environment:
- CUCM 11.5.1 SU5
- CUBE ISR4451-X (Cisco IOS XE Software, Version 03.16.05.S)
Sorry for my english :-)
I hope that anybody can help me. Thank you very much.
