SIP registration not sending username

[grd]

Hi,

We're changing SIP providers and struggling to get the new SIP registration working as it fails every time. The provider can see registration attempts from their end, but what they're getting is -

To: <sip:203.30.19.164:5062>
From: <sip:172.16.201.135:5060>;

rather than

To: <sip:203.30.19.164:5062>
From: <sip:service-number@172.16.201.135:5060>;

Both the SIP peer profile and the SIP config in MBG have the username/service-name in place but we can't seem to get the username sent at all. This looks like something fairly fundamental and probably a simple step that we've missed out somewhere along the line, but we've had no luck yet. Could someone please point us in the right direction?

Hi grd,
In the SIP Peer profile form is the registration number listed in the Local Account Information - Registration user name field?
It will need to be there and also under the user name for Authentication options.
also in the Network element is the SIP Registrar defined?

Hopefully this isn't sent to the provider, are you proxing through the MBG? It should replace the internal with an external if so
