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

Fri Aug 8 15:51:33 EDT 2008

You should only need allow-connections sip to sip, leave the others off unless you plan on using them.  They take up unnecessary memory.

That depends on the IOS version...

Try it...

voice service voip
 allow-connections h323 to sip
 allow-connections sip to h323
 allow-connections sip to sip
 allow-connections h323 to h323

Hi all and thank you for your answers!

So I'll need an IP2IP GTW because the Sip Provider give me username and password for the trunk authentication.

Now, the question is, can I add to the existing voice Gateway/SRST router the rule of an Ip2IP gateway, or I'll need to purchase another router?

Thank you all.

I thought the SIP in 6.1 supported digest auth on trunks?

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.

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

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
