voztovoice created an issue (kamailio/kamailio#4161)

As Asterisk PBX since version 20.12 supports **SHA-256** for digest authentication, it would be useful to be able to configure the authentication algorithm according to the device with which kamailio communicates.

It could be by indicating the two algorithms at the same time in this parameter:

**modparam("auth", "algorithm", "MD5,SHA-256")**

or have a function that allows activate one or the other depending on the device with which Kamailio communicates.

This because all the softphones I have tested so far do not support SHA-256
