Thanks all. It is too early to declare victory but based on my tests it looks like the Acme SIPConnect feature + Broadworks Alternate Trunk Identity is going to be the solution. On Tue, Sep 25, 2012 at 5:27 PM, PE <peeip989 at gmail.com> wrote:
Greetings fellow voipsters,
Have any of you done a SIP trunk integration between Broadsoft and 3CX? Or, more specifically, I have a customer with a 3CX device (don't ask) that is registered and I can send an INVITE, but their end denies the call (sends a 480 Temporarily Unavailable response) because it is having trouble routing it to the destination in the 3CX system. This is because they are expecting only the extension (4-digits), which I can send in the To: header but the SIP URI is the full, registered User ID so that the SBC knows how to get it to them. They are expecting only 4 digits in both the INVITE URI header and the To header.
I know I can create a complex/convoluted header manipulation with the SBC but it just feels like there must be another way.
Anyone know how to config the 3CX -- or even have a decent workaround -- to support this?
Thanks
