SIP Trunk to Provider (BT) British Telecoms through CUBE with CUCM 11

[jimihendrix1]

Hi I will be configuring a SIP Trunk to our local Provider British Telecom (BT)

Does anyone have an example SIP ITSP configuration I could have a look at to the SIP provider from CUBE's stand point, because all I have been given is a public IP address and been informed not to enable SIP ALG from the customer or provider, surely I need more information such as the below.

sip-ua

authentication username  ????? password ?????

credentials username  ????? password ?????

realm zzzz.zzzz.co.uk

retry invite 2

registrar dns:zzzz.zzzz.co.uk expires 120

sip-server dns:zzzz.zzzz.co.uk

Thank you!

This is what I typically reference but I don't see BT on the list.  Never hurts to ask them if they have done any interop testing and have their recommended configs as a starting point.

Thanks for this will reach out to the provider today and let you know how I got on tomorrow.

Appreciate all these links Greg.

Either way will let you know tomorrow.

Cheers!
