Yes it should.

My guess is probably you missed calling pjmedia_codec_speex_deinit().
I tried adding a new menu command like below in pjsua, and it seems to work:
case 'Q':
if (!simple_input("Enter new speex quality:", buf, sizeof(buf)))
break;
pjmedia_codec_speex_deinit();
pjmedia_codec_speex_init(pjsua_get_pjmedia_endpt(), 0,
my_atoi(buf), my_atoi(buf));
puts("Speex quality changed");
break;
But just a bit of warning again, the snippet above most likely
wouldn't work if there is a call with active media running in the
application.
