Intercom notification is quiet

[Justin078]

Hello! I have a Poly Edge E500 device that I'm wanting to be the recipient for one-way intercom calls.

Background information

The problem is that our phone system (Broadworks R24) is currently stripping the "Alert-Info" header so I have to do some hacky workarounds to get it to "work". Since the phone in question is only going to be used for one-way Intercom calls, I've landed on the following configuration:

On Broadworks

Turn on Silent Alerting. This sets the following header value:

Alert-Info:<http://127.0.0.1/silent>

On Poly

feature.intercom.enable="1"
voIpProt.SIP.intercom.alertInfo="http://127.0.0.1/silent"
voIpProt.SIP.intercom.alertInfo.encapsulateWithAngleBrackets="1"

I have tried it with just the above config, but it doesn't appear to work, so I have added the following:

voIpProt.SIP.alertInfo.1.class="answerMute"
voIpProt.SIP.alertInfo.1.value="http://127.0.0.1/silent"

This makes the one-way intercom work (by "work" I mean that the recipient auto-answers and mutes themselves) but the beep to notify the recipient of an intercom call is extremely quiet and short. This means that the recipient is only aware of the intercom call once the other end starts talking.

I'm still waiting to hear from Cisco on resolving the Alert-Info header being stripped, since it's a known header and shouldn't be stripped. Until then, I'd see if I could get some guidance from the community.

Any help is greatly appreciated!

Edit: The device is running PVOS 8.1.3

@Meghana_10, 

I opened a case almost 2 weeks ago with almost no movement and no response since February 26.
