The other assumption is that the CUBE is interfacing with a firewall doing NAT from a public IP address to the DMZ interface (172.18.0.16 in this case) and that the firewall has the appropriate ACL entries to permit SIP traffic from the ITSP to the CUBE router.

Feb 16, 2020 · As said in statement, when physical switch goes down where CUBE-1 and CUBE-2 Gig0/0 are connected, how CUBE-2 What if CUBE-1 is connected to SWITCH-1 and CUBE-2 connected to SWITCH-2. Both SWITCH'es are connected via Cisco Ether Chanel and VLAN communication between 2 switches is happening.

Activating “Run on All active Unified CM Nodes” on the SIP trunk and Route List. could cause some calls rejected, because the CUBE will accept calls only from the CUCM subscribers configured in the IP Address Trust list, in this scenario 10.1.5.17 and 10.1.5.18, the result the CUBE will reject calls from any other CUCM nodes such as 10.1.5 ...

During the call ' show voice call status' will show you what dial peers are in use. While show voice call status is very useful to determine the dial peers associated with the particular call, ' debug voip dialpeer inout' allows you to monitor the dial peer selection process.

The dial peer 301301 is associated to the tenant 200 using the voice-class sip tenant 200 command, the session target sip-server command instructs the CUBE to use the sip-server 10.1.6.16 configured previously in voice class tenant 200 to send outgoing calls to BB-CUCM.

Router 1 with FXO\FXS -> Router 2 (CME\CUBE) -> CUCM . Link between CME\Cube to CUCM is SIP Trunk . I am able to make calls from Phones registered to CUCM to Phones registered at CME and the Landphone connected to FXS port of Router 1 . Calls from Landphone to CME registred phones is also successful.

With "mode border-element", you get a full fledged CUBE. The way that you can test and see that with "allow-connections" alone the router is recognised as IP-IP GW is to register it to a gatekeeper. The GK will report the GW as "H323-GW" instead of "VOIP-GW".

A: CUBE is a media and signalling termination, it by default terminate media on one leg and add/remove headers on the outleg. Q: CUBE changes the source IP address of the RTP packets . A: Being a Media Termination , CUBE re-writes RTP headers while sending media to the outleg.That includes Source, destination IP adddress , ports etc.
