The C15 has SIP trunks, SIP lines, and SIP PBX lines. Whoever configures the C15 needs to make sure they build the configuration correctly.

I don't have any experience with the C15, but I've seen this with Sonus and other platforms, and they all have a way to turn off those messages if the other device can't handle, doesn't need, or isn't configured for it. In some cases you may have more specific options, but in other cases you just need to make sure you aren't using "SIP-T" on the trunk. Some venders call it something else, but I'm talking about when the SIP packet has an additional body portion containing ISUP parameters passed from the switch. You usually don't want that for a SIP-only application server like BroadSoft. Broadsoft may also have a way to handle these fields correctly now, but it didn't (or I didn't find it) the last time I looked into it.

There is a partner config guide from Broadworks in regards to a CS2000, but nothing on C15. I'm trying to use a partnering Telco's C15 as a routing NE, but I'm having signalling issues for both incoming and outgoing calls. On incoming calls, the INVITE message I receive on my AS looks standard except for a few entries in the TO header (there is NPDI and CIC information in the TO header that I don't usually see in INVITE messages). My AS responds "604 Not Found Anywhere". On outbound calls, my AS sends and INVITE to the C15. Like any other INVITE sent by the AS, the source port is an ephemeral port, like 35438, and the destination port is 5060. For some reason, the TRYING message sent back by the C15 has the destination port set as 35438, instead of 5060. Any insight you could provide would be appreciated.
