asterisk users - Feb 2005 - Odd behaviour between Grandstream and Xlite

Hi,

I've got an Asterisk box with grandstream and xlite clients on it.
No here's the thing:

  - I grey out all the codecs on the Xlite except for GSM
  - I call the Grandstream from the Xlite, the Xlite uses the GSM codec
and the Grandstream uses ulaw, with Asterisk doing the conversion,
everything fine
  - I call the Xlite from the Grandstrea, the Xlite ends up using the
ulaw codec as does the Grandstream

Why the asymmetrical behaviour?
Why does the Xlite accept a non-GSM call when it is set to do GSM?

Thanks for any help.

Rob

Actually it is worse than that.

Whatever codec I choose in Xlite, when calling the Grandstream it always
uses the GSM codec even if it is greyed out.

Whatever codec I choose in Xlite, when getting called by the Grandstream
it always uses ulaw even if it is greyed out.

I allow them to us any codec except speex (which seems to crash Asterisk
when used from an Xlite).

But it would be good if the user could choose their preferred codec
because with a softphone on a laptop sometimes you are on a connection
with good bandwidth to Asterisk and sometimes somewhere with terrible
bandwidth so you want to use a low bandwidth codec.
If Asterisk chooses for you then the codec choosing feature on the Xlite
is pointless.

and what about the phone config in sip.conf ?  
what codec do you allow them to use ?

I think * doesn't care what codec is grayed out in X-lite, her use what
sip.conf tell him he can
