----------------------------------------------------------------

My apologies.

The steps or actions was simply dialing the appropriate extension number with the below code. The behavior expected was for both endpoints to force to codec g722.

I also attached a PCAP from asterisk 13 where this works, and a PCAP from asterisk 16 where it's broken

Code (see attached - Code.txt. I did not know how to format here):

CLI Verbose on Asterisk 16 where this is not working. Neither of the endpoints were asked to change codecs:
(see attached - verbose16.txt)

CLI verbose on Asterisk 13 where this is working as expected. Same code. Both endpoints were forced to codec g722.
(see attached - verbose13.txt)

I would also like to point out that the asterisk 16 test was on 16.4.0. I also tried with 16.10 (latest) and experienced the same result.

> I am migrating from asterisk 13 and have successfully utilized the pjsip_media_offer function. Very simple code, not much else to it, and worked for years.
> https://wiki.asterisk.org/wiki/display/AST/Asterisk+16+Function_PJSIP_MEDIA_OFFER
> After testing an asterisk 16 machine, using exactly the same code, I am unable to get it to work. The CLI reads the code, but does not do anything with it. Furthermore, after analyzing the packet capture, there is no evidence of the asterisk machine sending an INVITE to renegotiate the codec.
> I downgraded back to asterisk 13 and everything started to work again
