             Summary: Subsequent MWI NOTIFY R-URI truncated
                 Key: ASTERISK-24877
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-24877
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Resources/res_pjsip_mwi
    Affects Versions: 13.2.0
         Environment: asterisk-13.2.0-5.fc21.x86_64 (branches/13 at 432614)

When subscribing to Asterisk MWI via Kamailio, I've noticed that after the initial SUBSCRIBE immediately after REGISTER, Asterisk will send a NOTIFY to the proper contact URI in the NOFITY R-URI.  However, when a new voicemail is created, the subsequent NOTIFY attempts truncate the contact URI in the NOFITY R-URI and Asterisk's NOTIFY is retried several times after never reaches the UAC and eventually gets a timeout back from Kamailo.

Initial SUBSCRIBE with immediate NOTIFY from Asterisk:
{code}
m: "Test User" <sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84OC82LK-2ehwl7NYDdNYDxNYlFUAm6UYzm0gme>;+sip.ice
...
NOTIFY sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84OC82LK-2ehwl7NYDdNYDxNYlFUAm6UYzm0gme SIP/2.0
...
SIP/2.0 408 Request Timeout
{code}

Subsequent NOTIFY from Asterisk after a new voicemail is left:
{code}
NOTIFY sip:172.16.4.7;line=sr-D8G7CE2.5PUeK-xuarl7NYDdNYDxNYlFUYoeUeQ8Cw.6DE2vDdyJDAa4TliwC84O SIP/2.0
{code}

The subsequent NOTIFY R-URI is truncated, missing the remainder of the original Contact URI:
{code}
C82LK-2ehwl7NYDdNYDxNYlFUAm6UYzm0gme
{code}
