[cisco-voip] CUCM 6.1 SIP Trunk to Provider

[Matt Slaga (US)]

It depends.  Does the provider give you user/pass credentials?  If so, UCM cannot do this, you will need IP2IP gateway inbetween.  If they are giving you a basic SIP trunk with only IP as creds, then most likely you can terminate directly to UCM if they use a compatible dtmf relay.

Subject: [cisco-voip] CUCM 6.1 SIP Trunk to Provider

 

Hi all,

  I'll need to configure a SIP trunk from a CUCM6.1 to an external provider, to route incoming call to a specified Phone.

 

Someone have already configured CUCM6.1 to do these? I need an Ip to Ip Gateway or not?

Can I use the Voice Gateway instead of IP to IP dedicated Router?

 

Thank you for your response

 

Best Regards

 

Alessandro Bertacco

Oggetto: [cisco-voip] Setting up a SIP trunk...anything special?

 

I am setting up a SIP trunk to a Cistera appliance (I believe they are using asterisk) in order for the box to dial out. The SIP trunk setup went fine and without incident. Is there anything else I need to do? Someone mentioned to me a while back that I would need something else like a transcoder.

 

Any pointers would be great.

 

Thanks,

 

Lelio
