Hi! Asterisk 1.0.9 (maybe also earlier versions?) contains a bug the effectively disables subscriptions for phones with multiple regististrations in place. When processing a "nonce response" as a result to an 407 authentication request Asterisk with SIP DEBUG reports "Found peer YYY" even though it should look at peer XXX to compare user credentials. Consequently a NOTICE is displayed with "Failed to authenticate user ... for SUBSCRIBE" (YYY and XXX share the same IP and port, only the user name differs). This bug is not present in 1.0.2 (for Asterisk 1.2 beta I cannot make a statement). Cheers, Philipp
