My (buggy :-) VOIP provider does not like REGISTER request to have
authentication digest from
previous registration and responds with "401 Unauthorized" response with a new
"nonce" field.
Asterisk sends new REGISTER with a digest based on the new "nonce" field but
gets 401 again
(and new nonce field :-) The only way to re-register is to send REGISTER
request without any
authentication digest, get 407 back (with new nonce field) and register with
this "nonce".
To get asterisk working with the provider I made the following patch to
chan_sip:

p->registry->hostname, p->authtries);
ast_set_flag(&p->flags[0], SIP_NEEDDESTROY);
Is it a right way? Or is it better to implement per-peer configuration option
like "reuse_digest=yes/no"?
