>          Issue Type: Bug
>      Security Level: None
>          Components: Bridges/bridge_native_rtp, Channels/chan_sip/General
>    Affects Versions: 16.4.0
>            Reporter: Frederic LE FOLL
>            Assignee: Frederic LE FOLL
>            Severity: Minor
>
> Bridge technology selection fails to select native_bridge_rtp, although both endpoints have negociated RTP with the same codec and ptime.
> Example :
> - sip.conf configured with A-Law allowed, restricted to 10 ms (allow = alaw:10)
> - Two SIP endpoints configured to negociate codec=A-Law with ptime=10
> - Re-INVITE for Direct Media does not occur after called party answer.
> The same problem occurs with other ptime values different from default value 20.
> Tested with Asterisk 13 or Asterisk 16 using chan_sip.
> Directmedia activation, in the same conditions, used to work in asterisk-13 branch (OK in 13.13 version), but recent Asterisk 13 versions also have the problem.
