IAX connection -> GSM only :-(

Asterisk Asterisk Support
1

Hi,

I have 2 Asterisk (1.4.4) servers running independently. Codec used are Ulaw and alaw, on both of them

I tried to conect the 2 * server together via IAX

Force in both IAX conf files,
Bandwith=high

Force the “users” -> ulaw and alaw
via
Disallow=all
allow=ulaw
allow=alaw

When I call another phone (on the other asterisk server) the com is only GSM ???

I have on the CLI :
requested format = ulaw
requested prefs = (gsm¦ulaw)
actual format = gsm
…

Any idea why ? Is there any other config file to check ?

Thanks for your help

Is this a typo ?

what does your IAX.conf look like ?

make sure there is no uppercase D in 'disallow’
or try to set them in [general] holder

Hi,

Thanks for your help
Here are a copy of my 2 IAX.CONF configurations…
As you can see, I force the 2 conf , to use ULAW and ALAW

Yes, sorry, It was a typo when I wrote : Disallow instead of disallow

Thanks again

Not sur ehow you are sending the calls but you need to add disallow=all to general and set the codecs to match, from what I can see server b doesnt even allow GSM
