so, we are sending a lot of faxes per day and it seems that we can just send two faxes simultaneously and then the message: “Outgoing Channels Are Busy. 0 Channels Available Now” orrcurs in the UCP-Fax-Dashboard.
I’am very happy with the Fax-Pro-Module, it was a worthwhile purchase, but i really need to set up this max-outgoing-fax counter to like… 4 simultaneous faxes or maybe higher.
We got two virtual extensions going out via the same CID (CID and the outgoing faxes are working perfect and without problems) but is there any way to set the “counter” for max-outgoing faxes higher than two simultaneous faxes?
I’ve found some possible settings that seems to be the the solution but… it was not.
First, i saw the “Extension Concurrency Limit” in the advanced settings. It was set to 3, i thought this was the problem, i set it up to 5 and created a new extension to test the fax. It was not the solution… After two simultaneous faxes, the third one just occurs the “Outgoing Channels Are Busy. 0 Channels Available Now” error …
Next question: Ive created a normal Chan_SIP extension to test it otherwise and not a single fax is going through the trunk when sending it from a regular chansip extension. Is it right that normal extensions are not able to send faxes when the extension is not registered on a softphone or device?
EDIT: Okay, even with a registered extension (chansip) on a softphone, faxes are not going out when the extension is not a virtual one… Don’t understand this - is anyone able to explain this to me?
