[asterisk-users] sip_header=value?

[Karl J. Vesterling]

There is a difference bwtween the SPA-941 which is a standalone desktop
phone w/ Speakerphone, and your SPA2100

What header value are you trying to set, and why?

Because the example I gave is for making the SPA-941 an intercom, and
also requires some changes in it's settings within the phones web
interface.  So of course my example isn't going to anything for your
SPA-2100 except give you an example of how to set a SIP header.

So now my question becomes, "What is it that you are attempting to do by
setting the SIP Header?"

Best Regards,
Karl J. Vesterling
