Hi Team,

Trying to use g729 and g723 but calls failed with 603 Declined.

when I setup the sip debug and check it gives us the error like below:

The patent has expired on g729, So either pay for unnecessary licenses (from digium or whatever) or install the open source version.

The asterisk16 package installed with the distro includes g729 – what version are you running?

Why are you trying to use g729 at all? IMO it is an annoying voice quality degradation. Can you use an IP phone, softphone or SIP app that supports Opus, which gives much better quality at the same bandwidth? Describe your system and its bandwidth limitations.
