[Asterisk-Users] Asterisk not populating nonce count

[Mark Moody]

Trying to register the Asterisk to the Cisco BTS 10200. The 
BTS challenges the REGISTER with a 401 Unathorized and 
sets “qop=auth” in the WWW-Authenticate header.

The Asterisk should reply with a nonce-count in the 
Authorization header of the new REGISTER but it does not send 
this field. 

What Asterisk configuration will force the PBX to send the NC 
value?

Thanks,

Mark
