>                 Key: ASTERISK-25182
>                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25182
>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Channels/chan_sip/CodecHandling
>    Affects Versions: SVN, 13.4.0
>            Reporter: Alexander Traud
>
> When you edit the allowed codecs, newly added codecs get appended, previously existing ones do not get removed. Or stated differently: On reload, the allowed codecs are not same as when Asterisk is restarted. 
> Steps to reproduce:
> # sip.conf with
>    disallow=all
>    allow=ulaw
> # start Asterisk
> # change sip.conf to
>    allow=g722,ulaw
> # CLI: sip reload
> # called Asterisk from a VoIP/SIP client
> # client gets ulaw,g722
> # CLI: core stop now
> I started over with step 2: Now, the expected order is offered (g722,ulaw). By the way in format_cap.c, the method format_in_format_cap() is a great starting point to find such issues. In this case, the code flow was:
> * build_peer, then
> * set_peer_defaults, then
> * ast_format_cap_append_from_cap, then
> * ast_format_cap_append, then
> * format_in_format_cap.
