[Asterisk-Users] chan_zap.c - echo cancelation getting in the way of dialing????

It seems consistant after dialing dozens of times that the call that
doesn't go through is the one the gets the log message  "No
echocancellation requested" (chan_zap.c) and the "Scheduleing
timer"
(channel.c)  in the middle of receiving the DTMF tones.

I'm now using the T400P card last week very simular problems the the T100P
(although I think I was actually loosing digits with the T100P card)

[Asterisk-Users] chan_zap.c - echo cancelation getting in the way of dialing????

The solution was provided by Martin Pycko, thanks Martin...



Yeah, edit the asterisk/channels/chan_zap.c

and find this context:

                            case SIG_SF_FEATB:
                                res = my_getsigstr(chan,dtmfbuf +
1,'#',3000);
                                if (res < 1) ast_dsp_digitreset(p->dsp);
                                break;
                            default:
                                /* If we got it, get the rest */
                                res = my_getsigstr(chan,dtmfbuf + 1,'
',250);
                                break;
                        }


change the 250 to 500 for a start and "make install" in asterisk.

That could help if not increase the value.
