[asterisk-users] Parallel dialoog with different Alert-Info headers

[Dirk-Willem van Gulik]

We have a couple of parallel ring settings (and this has worked well for eons).

Either in the form of

	same => n,Dial(SIP/1001 & SIP/1002 & SIP/1003 …..)

Or via a subroutine (below) that has a bit of extra logic:

	FOO = 1010 & 1019 & 1017 & 1033
	...
	same => n,gosub(sub-callout,s,1,(${FOO},”Ringing all class FOO telefons"))

Now I have two types of phones (different) era’s that require slightly different Alert-Info headers.

How can one introduce a layer of indirection at phone (extension) level that adds those headers ?

E.g. something like above 1010 mapping to

	; map internal virtual number to the real SIP dial
	[1010]
	..	SIPAddHeader(Alert-Info: <http://127.0.0.1>\;info=alert-internal)
	..	Dail(SIP/2010)

But still have the phones all ring in parallel. Any and all suggestions welcome.

With kind regards,

Dw.
