[Asterisk-Users] Odd behaviour between Grandstream and Xlite

[Rob Scott]

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
