"allow connection sip to sip" for CME SIP Phone

[konogoro1980]

Hi

I have to configure "allow connection sip to sip" to connect between two SIP phones.

In this case, CUBE license is not necessary?

I assume it is not necessary.

Let me clarify it just in case...

Regards,

Kaz

No you dont need CUBE license for that. Specially if your router is an ISR G2 (29xx, 39xx..) CUBE is not turned on unless you enter the command "mode border-element" command under voice service voip.

Correct.

Allow connections sip to sip is required, this is because SIP phones are in fact SIP dial-peers, which means we will be matching incoming/outgoing peers, hence the need for the command.

In the other hand, CUBE is not a requirement for it to work.
