SIP-trunking with Routit (Broadsoft/Broadworks) part 2

This week I've implemented a SIP-trunk at a customer site. This trunk is connected to a Cisco UC540. I could use almost all settings which I used in my lab setup. Before configuring the trunk I wasn't sure if the line setup would work with the CUE (VM-module) embedded in the UC540.

The customer has a simple IP-VPN connection with Routit, this means Routit supports a single IP-sgement with a maximum of 255 hosts and no routing of other customer IP-segments. I wasn't to sure if this was enough or if I had to use NAT because the embeded CUE lives on a different IP-segment. This UC500 was manually configured instead of with CCA. This meant some commands which CCA injects were missing. The following commands made the CUE work with the SIP-trunk without NAT:

SIP-trunking with Routit (Broadsoft/Broadworks)

Routit is a Dutch ISP which does not only offer Internetconnectivity for businesses they also offer hosted telephony and SIP-trunks. Although this is a Dutch ISP, their hostingplatform is an international one; Broadworks by Broadsoft. At the moment they are at version 19 I believe.
I already have experience with their hosted products but configuring a Routit SIP-trunk on a Cisco Unified Communication Manager Express (short CME) was new for me (not the SIP-trunk itself but connecting it with Routit). 
Everytime I have to configure a SIP-trunk for an ISP I haven't worked with it always take time to discover what it takes to get it working. In this case I haven't even looked at the tunable SIP-parameters and options but only at the authentication. The ISP didn't have any real examples available for setting things up on a CME (or UC500) only a snippet of a sip-ua config once sent to them by another partner.

It took me some time to get the authentication right (and some cursing etc. :-))
