I’m implementing Asterisk in several callcenters for our office. Because I have a legacy to come over from the old setup, I have to bare with some old functionality to make calls. It is not possible to have everything set over to the new system, which works great with Asterisk, so I’d really like to get this working.
The problem is, that we have several phones, which are connected to modems. These modems send the dialrequest to the server, the server dials the number et voila, the agent is talking to a customer. Some of these modems work flawlessly. They produce calls every single time. But some others just randomly produce calls. Sometimes one out of seven, but sometimes one out of four times works.
The times it produces nothing, I see just “nothing” happening in Asterisk. Sure, I see the phone got picked up, and that it is hung up again, but nothing in between. Apparently the modems just do not reach Asterisk. To me it is strange, that sometimes these failing modems are able to produce calls. I can remember to have read something about the amount of ms that zaptel reacts to incoming requests. Can that have something to do with it? Does that mean I have to recompile the drivers and change those values somewhere? Or are there other settings I could try?
I’m really starting to get nervous about this problem, cause management is starting to expect results… Anyway, any help would be much, MUCH appreciated!
