Using chan_sip, we are able to register with an NEC switch. When I try to REGISTER with PJSIP, the authentication is being rejected. Traces show it’s using md5 authentication. The packets looks almost identical. The one area that I suspect is causing the problem is the md5_cred for my pjsip.conf registration.

I’m using a Poco MD5 utility to generate the MD5 passing username:realm:password Where username is 3016
Realm is asterisk (default)
Password is 3016 which is the same as chan_sip’s secret The value I’m setting the md5_cred in auth section to is 63e8aedc77335879c93123055d21211d

Would this value match what chan_sip would pass as the md5 credentials?

Our sip.conf looks like the following…
[general]
context = NECTEST
bindaddr = 0.0.0.0
bindport = 5060
websocket_enabled = false srvlookup = no allowguest = yes debug = yes sipdebug = yes defaultexpiry = 480
deny = 0.0.0.0/24
permit = 10.100.102.0/24
permit = 192.168.9.0/24
canreinvite = yes callcounter = yes register = 3016:3016@10.100.102.82:5060/3016

[3016]
type = friend qualify = no nat = no host = 10.100.102.82:5060
defaultuser = 3016
secret = 3016
incominglimit = 24
accountcode = 33
port = 5060
context = NECTEST
dtmfmode = auto disallow = all allow = ulaw defaultexpiry = 480
insecure = invite fromdomain = 10.100.102.82
acl = acl6

Have a great day!
