CUCM (SIP Trunk) without VG or CUBE

[kokojatnika]

Hi,

Is there anyone configured cisco communication manager (CUCM) for direct calls to SIP Trunk provided by the Service Provider (Without Voice Gateway or CUBE)?

I am looking for configuration steps

Thanks

Trunk is trunk..
We use Direct SIP trunk to service provider as standart on our installations. We might use CUBE need split for trunk recording .
Ask Service provider their settings.
Some points, trunk specific..
-System/Security/sip trunk security profile (TCP or UDP signaling )

-System/region/Audio codec preference list, copy for editable list for correct order  ( + system/service parameters/cumc. some codecs too)

-Device/device settings/Sip Profile ( for trunk) .  IF allowed, Enable SIP options PING, It  is nice option to see if trunk alive...
-Device/trunk ... dependent on operator. Here i put only one iP for trunk, but depends on operator how many IPs they use.
