Problems with Fax Detection through Voicemail Pro 3

Voicemail Pro R9.1 SP12

I am having a problem that voicemail pro is not detecting fax tones and not sending to fax extension, keeps going to main hunt group

Through Voicemail Pro system preferences, under System Fax number i set it to extension 209
(no fax prefix or sub fax addressing)

Then through menu option, under touch tones, i added character "F", and transfer it to destination 209

In avaya manager under extension 209, i marked caller display type to DTMFF and under Equipment classification to Fax machine

but no matter what, the fax calls keep going into my main hunt group, is there something that i am missing

we can manually transfer the calls to the fax extension 209, but i want to figure out why the fax detection isnt working

I think i know what my issue is, i think for fax detect to work, the call needs to be answered first.

But during daytime hours calls go to live hunt group and not through pre-recorded greeting

only night hours and holidays go to prerecorded menus.

Is there any way for fax detect to work without call to be answered first, or after its sent to hunt group?

Crude but you could directing calls to a simple VMPro module with an AA containing just F to 209 and a 1 second timeout that transfers to the huntgroup. Depends on your call density (you'd need free channels for the likely number of calls that might arrive in the same second).

i will try this, thank you, i have 10 channel sip trunk license, and my sip trunk provider can handle that load, but most likely will never be using more than 3-4 at once.

I think I would set the time out to 4 or 5 seconds as the tone is .5 seconds on 3 seconds off. One second would probably miss the tone unless your very lucky.

shoot, your right, 1 second not enough to detect, i just tested it

 

[joe2938]

I would think at least 2 rings as caller id needs at least that to detect

 

[edlee321]

i guess i will just make a prerecorded menu prompt for daytime hours as well

 

[budbyrd]

The two rings will happen before the VM answers, so I wouldn't worry about that. 4 or 5 seconds should do it. Record a ringback and use it for the VM prompt if you're woorried about call confidence.

Make a 10 second wav file of ring-back tone. Play that as the prompt for the menu, with a zero second time out to the group, and the F destination to the Fax.

thanks everyone, this is great advice!

The IP Office will have obtained the CLI information before it passes the call to the voicemail server, so no need for 10 seconds. The only unknown is how many seconds of fax tone the voicemail server needs before it decides a call really is a fax call. Yes, mask the pause with a "Welcome to Acme Inc." prompt but its probably just a couple of seconds needed.
