Call through pbx with phone card, want to edit!

[Mr. Kalle]

Hi.
I have a "phone-card" -app in my HTC Wildfire, called opti-caller, that makes my outgoing calls route through my company's switch board (pbx). When I dail a number, the app first dail an access-number to the pbx, gets a 5 sec. long dail tone and then continues with the number I dailed.
It works fine, but that 5 sec. dail-tone is annoying! According to the company that makes the app they can't do anything, because the app uses the phones own dailer.
Anyone have any idea how to shorten this dail-tone to like 1 or 2 seconds?

Any tip would be appreciated.

It would have to be programmed thru the pbx itself, or the app dev could mask the dialtone noise. It is a timer in the pbx which can be shortened or lenghtened or turned off so there is no dialtone heard. Dialtone you see, is not really needed to make calls, it was only ever there for customers to know for sure they were connected. and thats why it is heard even on most disa apps today, so the user knows when he has hit the switch .anyway, I'm a pbx tech, so I program these things everyday, it's called DISA on most pbx's...

also if your office pbx goes out a pri, try putting a # sign at the end of the dial string to see if it sends the call out faster, the pbx has a timer that waits to see if extra digits will be dialed before it sends it out and the # sign tells the pbx that is the end of string do not wait for the timer which is usually set for 3-5 seconds. Most pbx's actually collect all digits first then spits them out because sometimes they have to reference different trunk groups or restriction groups to see how to route a call or even if it is allowed, ie long distance or overseas restrictions. hopefully this isnt info overload...if any questions ask , be happy to help

Hi bbrosen, and thanks for your answer.
The thing is, I'm a pbx tech too. (Aastra Bp and LG iPECS)
I'm testing this app in our own pbx, and want to shorten the dial-time as much as possible. We use a sip-trunk, the # does help, in this case with 4 secs. We have tried it on bri/pri too, it makes a difference there too.
But, to clerify, there is no sound when the app calls the pbx, then it makes a 5 sec pause while you hear the dial-tone, before it dials the 0 (trunk-access) + my dialed number, and in this part you hear the dtmf-tones. Of course I could try to mask the dial-tone in the pbx (not sure if it's possible), but there will still be this 5 sec. pause!
This pause is made by the app/cell phone, so I have to shorten it there, but how?
Android and cell phones is not my cup of tea Any ideas?
