A lot of phones support the Alert-Info text so you can customize ring tones for different calls.
It would be nice if we could configure the Alert-Info from 3cx. it would be nice if it can be custom per ring group but it will be an whole improvement if there can be an difference in internal and external calls.

"A lot of phones" sounds like "all PBXes 20years old"
Could you please be more specific?

Thanks

All the snom phones (3x0 and 8x0) support the alert-info.

Snom, Aastra, Linksys, Cisco, and Polycom phones support this and support for changing this is built into FreePBX/Asterisk.

How it should work and be configured?
Any suggestions?

From the RFC: http://www.ietf.org/rfc/rfc3261.txt

20.4 Alert-Info

When present in an INVITE request, the Alert-Info header field
specifies an alternative ring tone to the UAS. When present in a 180
(Ringing) response, the Alert-Info header field specifies an
alternative ringback tone to the UAC. A typical usage is for a proxy
to insert this header field to provide a distinctive ring feature.

The Alert-Info header field can introduce security risks. These
risks and the ways to handle them are discussed in Section 20.9,
which discusses the Call-Info header field since the risks are
identical.

In addition, a user SHOULD be able to disable this feature
selectively.

This helps prevent disruptions that could result from the use of
this header field by untrusted elements.

Example:

Alert-Info: <http://www.example.com/sounds/moo.wav>

There are 2 options for integration

1: Simple: only differance between internal and external calls, so somwhere in the options you should be able to choose for "Alert-info value internal calls" and "Alert-info value external calls"

2: Advanced: Per ringgroup, so per ringgroup it should be possible to choose an 'Alert-info value'.

Then an admin can specify the value of the alert-info and they can learn the value to their phones, or 3cx should add the defaults in the phone provisioning templates.

Granstream phones also support ALERT INFO for distinctive ring tones.

How about a "check box" in the options for each trunk group you build... External ring signal to be applied for this trunk group. That way, if you had a trunk group with calls coming from another "company" PBX (bridged trunks) it could be left to ring as an internal call.

[KerryG]

I would simply add an Alert-Info field to ring group and queues. Anything that goes through one of those is, by default, an inbound call. Direct extension and extension to extension calls wouldn't go through a group and therefor not have Alert-Info applied to them. Its not as complete as having multiple options per extension but it would be a helluva good start.

Is there already for the issue "Alert info".
All of the customers who wan`t to make the step to 3CX, wants a difference ring for internal/ external incoming calls.
