Can I customize the value of AVP when used as lac

[risetek-wangxu]

Hello everyone
I used xl2tp(version 1.3.15) as lac,can i customize the value of AVP?

The following file is specifically for avp
https://github.com/xelerance/xl2tpd/blob/master/avp.c

and the 22 of avp is 'Dialing Number', I want to customize a dialing number, and then initiate a connection to lns

such as:
[root@localhost ~]# vim /etc/xl2tpd/xl2tpd.conf
[lac testvpn]
name = test
lns = 103.23.82.1
pppoptfile = /etc/ppp/peers/testvpn.l2tpd
ppp debug = no
require pap = yes
hidden bit = yes
Dialing Number = ‘460018132424026’ // Of course, writing this way will report an error, I just want to achieve this effect

Can my idea be realized in this version of 1.3.15? how? thanks,thanks,thanks
