Can't listen to voicemails on iphone

Posted by k3leland on Wed, 03/10/2010

I am unable to listen to voicemail files through the web page from an iphone browser. There seems to be something about the way get_file.cgi delivers the file that the iphone doesn't like because I was able to listen to the same exact file emailed to my iphone, therefore I know its not the format of the file but instead something else.

That is correct. In order to get the attachment to play I had to change voicemail.conf.

I changed the following line from:

format=wav49|gsm|wav

to:

format=wav|gsm|wav49

Apparently the iphone doesn't like the wav49 codec.

not true. I listen to wav49 files in email all the time on an iphone. Maybe safari itself lacks the ability to use the gsm codec (wav49 is gsm encoded wav formatted file). In fact, thats the single format that is attached to the email you listen to. Dont bother with gsm at all, why record every message 3 times taking up so much disk space.

you could try format=wav|wav49

but I always just use wav49 because 1) you need it for the email attachments, and 2) makes no sense to record in wav49 AND a pcm wav format that is 10x the size of the wav49 file.

the only exception is STE installs where recordings are important and I want to preserve audio quality.

Yes thank you, that was helpful, I was able to listen to all the attachments that I was having trouble with by using the native iphone mail reader instead of safari.

Can you, or anyone else, download voicemails from the web portal?

didnt work, tl sends the file just fine.. for whatever reason safari thinks its a movie and the movie player rejects the format. Had it handed it off to the correct application (the one your email app sends it to) there wouldnt be a problem. I think the actual problem is with safari mis-identifying the correct app to handle that filetype (microsoft wave gsm encoded)
