TAPI HookFlash

[ICODev]

Hi,

I have an IP Office V9 with analog lines. I need to do hookflash transfer (Centrex Transfer).

I have program a button that execute a Flash Hook, and with this button I can manually do my transfert, example: FlashHookButton + *11.

Now my problem is that this does not work in my application using TAPI, im using GenerateDigits("!*11") but it does not work, the ! for HookFlash does not seem to do anything (I can only hear the DTMF for the *11, ! is silent and does not do anything).

Any help is welcome.

"OffHook Station" is enabled in the user telephony pannel.

TAPI doesn't support that

TAPI does support that, I was doing it on my old Norstar Central.

Do you mean that Avaya TAPI driver does not support that? If so, is there a work around for this, like pressing a programmed button of the phone over TAPI?

 

[intrigrant]

AVAYA TAPI does not support that. It is not a Norstar. No virtual buttons either, no way to do this.

Damn, how is it possible that Avaya miss this basic command?

Im programming a 911 Central Phone Interface, our customer is switching from Norstar to Avaya IPO and we need to do this Centrex Transfer.

Do you have any link/source that say Avaya does not support this? And are you sure there no workaround, even if its a dark one.

And thank you very much for your help.

Perhaps this is the time to move the customer out of the 19th century & migrate them to ISDN?
& while you are replacing the Norstar do yourself a favour and do not succumb to the temptation to replicate a key an lamp system.

We are not the provider of the analog centrex line, and this is what Bell 911 provide, we have no option.

We are the developper of the application, not the provider of the 911 service and not the provider for the telephony system.

So they are going to have 911 calls hanging on the reliability of Avaya's TAPI.....oh dear, I wouldn't do this

 

[ICODev]

So Avaya TAPI drivers are that bad? Because everything else work well so far, working with 26 lines and 4 stations without any problems. Using TAPI3.

On a non centrex line in my lab I can do normal transfer and conference without any problem as well. Never got a delay or bug with the Avaya TAPI so far. The HookFlash is my only issue.

 

[amriddle01]

I have seen issues with TAPI just stopping working out the blue and when you go to re-install it just goes into an install... "reboot to complete" loop that completely unistalling can't even stop. Mainly on newer OS and 64 bit machines though

 

[ICODev]

I see you had alot of problems installing the drivers. In my lab I have install on Vista 64 bit, XP 32 bit and Win7 32 bit. Then we have install 4 other computer on Win7 32 bit, never had a problem. Even work on a XP Virtual PC.

Never found the TAPI3 driver for 64 bit, so the 64 bit computer is using TAPI2, others are using TAPI3. But in production all PC would be 32 bit anyway.

If only we could find a solution for the HookFlash. I have open a paid ticket on the Avaya WebSite, waiting for an answer.

Avaya TAPI drivers aren't bad, in fact they are very stable but there are no centrex features in them as the system is developed for the 20th century. Centrex lines were not possible until Avaya went to the US market with release 3.0. TAPI has not been enhanced after version 2.1.

So what you are trying to do is initiate a "Star Code Transfer" on the CAMA Trunk provided by the Selective Router which uses the CENTREX signaling standard. For those interested, ISDN is NOT an option, as the 911 infrastructure that was developed in 1968 has gone through very little technology refresh over the years. That's another topic, and you can read my Blogs at

if you want the details on that. ;-)

Now back to the problem. I was just in a meeting with a 911 developer yesterday, and the topic of Star Code Transfers came up. They confirmed they are delivering this functionality on the IPO today, through their software, as are at least one or two other developers that I am aware of. Based on this, I would confidently say this can be done as this is the way PSAP transfers occur on the 911 voice network.

If you cannot get this to work, or need assistance in supporting this functionality, I would suggest that you engage the DevConnect Product support team, as that is part of your annual Avaya DevConnect membership. If you need an escalation, please let me know. Emergitech (

is the company I met with yesterday. If anything, you may be able to contract them to assist you, although, beware they sell what you are trying to develop.

Thank you very much Mark J.

This was very helpfull, I have open a support ticket with DevConnect and I think they have already contact you for more info.

 

[Avaya911PLM]

Yes, they called and I spoke to the support engineer that is assigned. FYI, here's one point that was made clear:

CENTREX Service is basic analog service with some extra features that can be activated after a hookflash on the CENTREX TRUNK
The TRUNK Hookflash is NOT associated with the station hook flash
The Analog Trunk (if attached to a gateway) must get it's hookflash from the gateway and NOT the IPO.

Once I got the engineer to draw this out and realize the difference between the trunk side hookflash and the station side hook flash the problem became very clear.

I think a big part of the problem is when people put a PBX in front of a phone on a CENTREX, they then expect the 'phone' to operate the same as it does when a phone is connected directly to the line.
