Re-registration timeout not working on SIP Trunk to ITSP

[metalium2007]

Hello,

I'm currently configuring a sip trunk to an ITSP with sucess. The only problem is that the registration expiration timer sent from the ITSP are 180 seconds and even if i change that value in my configuration I always send the re-registration request only after 240 secs.

sip-ua

credentials username <user> password 7 <pass> realm <realm>

authentication username <user>password 7 <pass>

no remote-party-id

retry invite 2

retry register 10

timers connect 100

registrar ipv4:xx.yy.zz.ww expires 180

sip-server ipv4:xx.yy.zz.ww

host-registrar

show sip-ua register status

Line                                            peer         expires(sec)   registered           P-Associ-URI

================================ ========== ============ ========== ============

<my_reg_number                        20007           229             yes

Do you have any hint about this parameter changing? some bug or wrong config?

Thank you!

Hmm...not sure what version of IOS you have but

please check if you can configure following...

sip-ua

  registrar  ipv4:xx.yy.zz.ww expires 180 refresh-ratio 50

with this IOS will send the reg refresh at 90 sec...

Curious, why we are negotiating 240 sec when we are configured

for 180sec? Did u run ccsip mess debugs on IOS and check

Expires field in the Reg and Ack msgs ?

HTH,
