BT SIP Lines

[DaveAvaya123]

Hello

Does anyone have a setup guide for BT SIP lines. I am following one they have provided and its out of date by a few versions.

Cheers

The setup doesn't change in later versions of programming or that document, it should still be relevant

 

[DaveAvaya123]

Thank you.

I have configured the SIP line as in that document but the SIP line wont register. Just to check I should be able to ping the uk.dc.sipconnect.hipcom.co.uk address from the IP or has BT disabled ping requests?

Cheers

Do you have a DNS configured on the IPO?


BAZINGA!

I'm not insane, my mother had me tested!

 

[DaveAvaya123]

Yep

 

[amriddle01]

They don't respond to pings...helpfully

 

[DaveAvaya123]

Thats helpful of BT. I am thinking its the customers firewall that they wont let me have access to. The phone system is system status is showing the resolved name as the IP address so that should be fine.

Thanks for the help

The dc here uk.dc.sipconnect.hipcom.co.uk would suggest they are direct connect (IP authenticated) as oppose to registered trunks, so you wouldn't see them register in that scenario

 

[DaveAvaya123]

They have sent me a user name and password for the sip lines. I will try it with out and see if it makes a difference.

 

[amriddle01]

If you have a username and password they will be registered, I usually use uk.ic for such trunks though

 

[DaveAvaya123]

That weird then as i have a user name and password but they have pointed the dc ip address at the customers ip. I have changed it and its now its showing the lines in service but they have not removed the network call forward that was ment to end on friday. Another job being delayed by BT.

Here is an exported template of our working BT trunk, you just need to import it and change the credentials to your username and password... and possibly the line group ID's, but that works 100% as long as you have a valid IP route, if not something is blocking it or you have dodgy credentials

 

[DaveAvaya123]

I have set it all up and still wont register. Is there anything special you need to do if using a juniper firewall? The customer says they have set-up a static NAT to the phone system and opened the relevant ports.

Cheers

Don't know, never used one.... but make sure any SIP ALG/packet inspection is off. FYI you shouldn't need to open any ports or do any NAT mapping, it will traverse NAT fine once the router/firewall stops messing it up, we never do either anyway

FYI (on a sort of related note), BT/Hipcom have just changed the entire platform they use to provide SIP services, during which they have started sending caller ID as +44123456789 as oppose to 44123456789 and so Cisco and Mitel systems using the platform (many) now don't match caller ID against their directories, Avaya kit knows/understands the number and so it still works fine
