I think we understand each other now :-)
My problems at the moment are twofold:
- I'm not receiving the DTMF tones at this moment. I would assume this has
something to do with the Alcatel phone station. If anyone has some experience
on this matter then I would be very glad to hear about it.
- The code I currently have ( a state machine, sound recording/playback etc.)
assumes that the sound is received on a device with a particular deviceID, and
outgoing sound should as well use a particular deviceID. When multiple calls
enter the picture, my understanding is unfortunately not too deep. Would I be
OK with just one device, wouldn't the sounds from the different calls get mixed
up?
Other than that, it's all fine and dandy :-)
Regards,
Daníel

PROTECTED]: Re: [sipxtapi-dev] Multiple simultaneous calls to the same
numberCC: [EMAIL PROTECTED] ok. I understand now.You're going to have a
PSTN->SIP gateway -> this dictation recorder sipXtapi UA.This dictation UA will
need to handle (from what I've been hearing from you), many incoming calls -
initially fine with 16, but final product will need to handle 50-100 or more
simultaneous calls. You want a way to record said calls from the dictation UA
itself, and you want to interpret DTMF tones.This all sounds perfectly do-able
by sipXtapi. It'll require a bunch of work at the application level to perform
the recording (and/or see Jaro's record patch), you'll need to do something
based on the DTMFs received - this also is easy to do with sipXtapi, afaik.
You'll set up your UA so it has 1 AOR, but multiple internal lines, and when a
call comes in, you'll transfer it to one of the internal lines for handling.
When new calls come in, you'll do the same, up to the maximum (currently 16,
but can be changed in code). Once the maximum is hit, the sipXtapi call
manager will send (I believe) a 486 (busy indicator) back to the remote user
(doctor).

Re: [sipxtapi-dev] Multiple simultaneous calls to the same numberCC: [EMAIL
PROTECTED] default maximum number of calls is 16, but there are people out
there using sipXtapi with upwards of 100 calls or more (there have been reports
of someone receiving several hundred calls). If you wish to receive more than
16 calls, you will have to change:
#define MAX_MANAGED_FLOW_GRAPHS 16to some new value.I also believe
that the mixer currently can mix only 10 calls, but this also can be easily
changed. How exactly is your dictation software working with regards to calls?
I don't entirely follow what sort of requirements you need from sipXtapi or
other SIP stack.

My application will not be dialling, it will only receive phone calls. Ideally
it should allow many users calling at the same time, presumably from different
phone numbers. The application in question is a dictation solution for doctors,
where doctors call this particular number to dictate a report which is then
transferred to a secretary. It would be very limiting if only one doctor could
dictate at the same time... Regards,Daníel
