[asterisk-users] Asterisk Manager gives event PeerStatus: Unregistered Cause: Expired

[Jonas Kellens]

Hello Joshua

this is the SIP REGISTER at 11:10:45

REGISTER sip:tstv7.domain.tld SIP/2.0
Via: SIP/2.0/UDP 
192.168.1.18:5060;branch=z9hG4bKcfd4c09d669ce595351ea3b2aba3e245;rport
From: <sip:testacc7700105 at tstv7.domain.tld>;tag=3630891428
To: <sip:testacc7700105 at tstv7.domain.tld>
Call-ID: 3270725701 at 192_168_1_18
CSeq: 452 REGISTER
Contact: <sip:testacc7700105 at 192.168.1.18:5060>
Authorization: Digest username="testacc7700105", 
realm="tstv7.domain.tld", algorithm=MD5, uri="sip:tstv7.domain.tld", 
nonce="42a70292", response="e2945dacd2d95b47a4801b2471070702"
Max-Forwards: 70
User-Agent: C610 IP/42.075.00.000.000
Expires: 180
Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, REFER, SUBSCRIBE, NOTIFY
Content-Length: 0

I see here "180".


I also see in the SIP debug traffic that a SIP REGISTER occurs every 180 
seconds, which is what is set in the SIP client.


This "Expired" notice occured only once at 11:20:55. How come this 
happens only once ?

And why should there *ever* be an "Expired" if there is a SIP REGISTER 
every 180 seconds ?!



Kind regards.
