[asterisk-users] Polycom firmware 4.0.1 and paging

[Mike]

In case anybody was following this thread, or someone Googles it in the
future, here is the solution:

This worked fine with Polycom firmware 3.3x: 
exten => s,n,SIPAddHeader(Alert-Info: <Ring Answer>)

For firmware 4.0+, apparently I needed to add info=, i.e.:
exten => s,n,SIPAddHeader(Alert-Info: info=<Ring Answer>)

Simple, yet quite obscure (for me at least).
