[cisco-voip] VMWI on analog phones with VG224

[Ahmed Elnagar]

hello jason;
 
The phone is working normally for all of the normal options (off hook, on hook, dialing, answering calls,...etc) the problem is with the VMWI signal that is maybe sent 90 volt (or even in some models higher) it is an FSK signal with 90 v that signals the analog phone to light the lamp whenever the user has a voice mail. in VG248 it supports the 90 v signal but for the VG224 it doesnot, so it is not affecting the over all operation of the phone just the VMWI is the affected feature.
 
Thanks and Best Regards

What make/model phone or region/country uses 90 volt phones? I did a google search and see some intercom/hospital phones. I had never heard of 90 volt until your posting, something to watch out for! -jason

Hello kenneth;

Thanks for your reply, the problem was that the VG224 only supports FSK with 24 or 48 volt and the analog phone that I was testing was using 90 volt by default, this phone works well with the VG248 as it supports this high voltage but not the VG224.

Hi Ahmed,

 

I have VMWI working on an ISR router with FXS ports (VMWI will work on a VG224 as well). Basically below are the requirements:

 

·         The Cisco Gateway must run IOS version IP Voice T strain (not SP Services on ISRs) 12.4(6)T or later (I tested 12.4(11)T2)

·         Cisco CallManager version must be version 4.2 or later (I tested CallManager 5.1.2)

·         Any version of Unity (I tested Unity Connection 1.2)

·         Must use SCCP(Skinny) as the gateway protocol, and NOT MGCP

 

Here is an output from the gateway(MWI refers to stutter tone VMWI needs to be "ON"):

 

pstn#show stcapp device voice-port 0/3/3

Port Identifier:  0/3/3

Device Type:      ALG 

Device Id:        4

Device Name:      AN17598075F0183

Modem Capability: None

Device State:     IS

Diagnostic:       None

Directory Number: 1005

Dial Peer(s):     101 

Dialtone after remote onhook feature: activated

Last Event:       STCAPP_CC_EV_CALL_DISCONNECT_DONE

Line State:       IDLE

Hook State:       ONHOOK

mwi:              ENABLE

vmwi:             ON

PLAR:             DISABLE

Number of CCBs:   0

Global call info:

    Total CCB count      = 0

    Total call leg count = 0

 

Thanks,

Ken.
