Topic: Alert-Info problems

[jono]

Hello,

I'm having some problems getting a trunk's Alert-Info working.

I have set the Alert-Info as <http://www.mywebspace.co.uk/folder/tone.wav>

Below is the sip trace from the Snom handset. You may see that a space is inserted after http://

Hi

I must admit, we've never tried to get a Snom to use an external tone.  However, the strings we successfully use for Snoms look like this...

Code: [Select]

Alert-Info:<http://127.0.0.1>\;info=alert-external
Notice that we include the Alert-info: string and we encapsulate the uri in a <> wrapper.  This is pretty much what we got from Snom and it works fine for selecting the on-board ring tones.  It will select the tone which is associated (in the above example) with the Snom's alert-external variable.  You can set this in the phone's "Preferences" section or via provisioning. 

I don't know why the space is creeping in to your URL.  There is no overt code in the handler to manipulate the string itself.  We simply take what you give us and insert it into the SIP header.

Kind Regards

Thanks for that. Pointed me in the right direction.

Alert-Info:<http://www.mywebspace.co.uk/folder/tone.wav> works

I had thought that in the Trunklines set up I didn't need to include Alert-Info: as it is implied by the name of the field.

so...

can you get it to play any old .wav file?


Best

Yep, so long as it's a standard 8 kHz mono 16-bit sample WAV file.

I use it primarily to make DDIs sound different from, say, the main incoming ring group - something you tend not to be able to do on legacy systems.

cool
