[SR-Users] phonenum module erratic behaviour with 5.1.2

[George Diamantopoulos]

Hello all,

It seems that the phonenum module in at least 5.1.2 (haven't tried previous
versions) is behaving somewhat erratically. More specifically, if there are
any references to any phn PVs with the key other than "number":

if ( phonenum_match("1-484-555-8888", "src") ) {
xlog("number norm: $phn(src=>number)\n");
xlog("number country: $phn(src=>country)\n");
dbg_pv_dump(30, "L_ERR");
}

kamailio will not start:

$phn(src=>country)

If I comment the offending line, all is well, but when dumping PVs with
dbg_pv_dump(30, "L_ERR");, only $phn(src=>number) is listed, not the other
keys (country, operator, region according to the docs)

However, what is more disturbing is that phn(src=>number) always contains
the string provided to phonenum_match() function, even if invalid
characters are included, with no normalization. For example:

phonenum_match("14~8%^88", "src")

will result in dbg_pv_dump reporting:

"$phn(src=>number)": "14~8%^88"

Please note that I'm using sipwise's debian repository for stretch for
kamailio, and debian's stable stretch repository for libphonenumnber
(currently at 7.1.0-5+b1). I have also tried building current
libphonenumber myself (version v8.9.2), but the result is the same.

Is this a bug? Or am I missing something? Thanks!

BR,
George
