Envox Developer Blog

After getting a good price for the missing fax licenses for HMP (Dialogic) we got further support hints from envox syntellect but we are a little bit hopeless to get fax running …

The help text of Syntellect (formerly known as Envox) concerning fax is not very helpful and sometimes quite confusing, when you just want to recieve fax messages with the same script that should also answer voice calls.

The support of Syntellect (and their partner Bressner) was unsatisfactory: long waiting times for an answer of the Syntellect experts, and some of these answers weren’t helpful at all (e.g. similar abstract information as in the help files)

Bressner Technology informs us they did not sell us the neccessary HMP (Dialogic) licenses which are necessary for receicing faxes on the envox syntellect plattform.

answer from Bressner Technology: no licenses needed.

envox syntellect requests to see the code – hopefully they are willing to log-in and check!!

we got some hint that maybe we don’t have the right  licenses on our envox syntellect platform…

Unfortunatly are these instruction well known – and I am not sure what he means with: … it is not an exact sience … ???:

With regards to detecting the difference between voice and fax, it really is not an exact science and our platform really just provides the API, it doesn’t control the low level Dialogic stuff.
Having said that, what I would suggest is:
1. EnableFeature > Specific > Enable tones > Fax CNG Calling tone (1100Hz).
2. WaitCall block.
3. Play block (you may want to play a greeting if a caller may be dialing in.
4. Continue code for ‘voice’ flow.
5. In the Event Handler, handle FaxRecvTone event and pass through the   EndEventProcessing block, then go to FaxRecv block and continue as required.
Also, handle Disconnect in EventHandler block to ReleaseCall, pass trough EndEventProcessing and goto WaitCall block.

envox syntellect is still working on an answer for our fax problem. At least Bressner Technology says so.

trying to implement the end user fucntionality receicing fax fails. Using the sample in the help file does not work.

The answer from envox syntellect support is that he thinks the help file description is extremly helpful …

So he will get the code to check.

I got new information from our support partner  Bressner Technology – he will try to get answers … and a solution

Our workaround for converting wav to mp3 with a BATCH-Script works now – We got no helptful information from syntellect, how BATCH-Scripts with parameters are triggered. To ensure that the parameters are correctly identified by the BATCH-Script, they must be written between double quotes – the problem was, that a string already has to be between double quotes. To write double quotes within a string, you must write two double quotes, as we found out (trial and error…)

e.g. “Hello “”world”"”      for:                    Hello “world”

Unfortunately this information neither is in the syntellect help files nor was syntellect able to tell us…
