While trying the following code with sdp content-length of 2978 : -
$var(telephone-event) =3D $(avp(sdp){re.subst,/.*a=3Drtpmap:([0-9]+) telephon=
e-event.*/\1/s});

kamailio -v
version: kamailio 5.1.4 (x86_64/linux)

got the following errors: -
ERROR: textops [txt_var.c:80]: tr_txt_eval_re(): PV value too big 2978, incre=
ase buffer size
ERROR: <core> [core/lvalue.c:346]: lval_pvar_assign(): non existing right pvar
ERROR: <core> [core/lvalue.c:404]: lval_assign(): assignment failed at pos: (=
424,27-424,91)
ERROR: <script>: telephone-event: 0

This is due to the fixed size of 2048 modules/textops/txt_var.c at line 48 : =
-=20

'''#define TR_TXT_BUF_SIZE	2048
	static char tr_txt_buf[TR_TXT_BUF_SIZE];'''

Please can anybody check..
