I guess this would do the trick:

diff --git a/src/pbx_impl/ast111/ast111.c b/src/pbx_impl/ast111/ast111.c

                                if(!strcasecmp(frame->src, "ast_prod")) {

it's a bit of a simple patch, but tbh that debug message is not really adding anything to the process either.

well its easy for you , its not easy for me , im a starter ! thanks for the reply but
as my pbx is issabel the location of ast111.c is /usr/src/chan-sccp-chan-sccp-968caa4/src/pbx_impl/ast111/ast111.c
i guess that if i gonna add this lines below it will be ok ? at line 840

Hi there,
Sorry about making assumptions.
In the sccp_astwrap_rtp_write function you can remove lines 860 and 861, which contain:

                       } else {
                                pbx_log(LOG_NOTICE, "%s: Asked to transmit frame type %d ('%s') with no samples.\n", c->currentDeviceId, (int)frame->frametype, frame->src);

That should suppress the extra logging.I hope that makes a little more sense ?
In the meantime i will think about removing them in general.

Note: asterisk-11 support has been dropped by digiium some time ago and chan-sccp support for asterisk-11 is no longer being maintained. So please start making plans to upgrade to asterisk-16 or asterisk-18.

Little tip about reading diff/patch files: the "+" or "-" at the start of the line denotes what needs to happen, So "-" means remove this line and "+" means add this line. In this case, i am remarking out the lines 860 and 861, so the effect would be similar to just removing the lines in the first place.

@npanagiotidis81
I have reconsidered the issue, and committed a patch to the repository.
You can do:

cd /usr/src/chan-sccp-chan-sccp-968caa4/
git checkout develop    # to undo your local changes
git pull                # to fetch the latest version

Thanks for reporting the issue and making me aware

[npanagiotidis81]

thanks for the support !
