Sip registration issue

[bagnolini]

My Sip account is perfectly registered with the Sip provider, but the problem is that the router every time tried to registered another account (line 120) and the provider block the account.

How can I do for block this issue?

I've attached the configuration

This is the show sip-ua

cisco2901#show sip-ua register status

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

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

120                               40003       128           no

60510988031                       -1          2100          yes

Hello.

You can stop the router trying to register the ephone:

voice register dn  4

number 120 no-reg primary

Ok, I needed also to reload the router (I don't know why but after that everythings work fine)

Thanks

OK good. I suspect the registration would have disappeared after expiry (marked as 128 seconds in your example above)
