Steve, My asterisk server is on public internet, since applying this patch I see my asterisk is sending re registration requests every 14 seconds.
Nov 10 18:14:30 NOTICE[1089948224]: chan_sip.c:4023 sip_reregister: -- Re-registration for [EMAIL PROTECTED] Nov 10 18:14:30 NOTICE[1089948224]: chan_sip.c:6795 handle_response: Outbound Registration: Expiry for sip.broadvoice.com is 159 sec (Scheduling reregistration in 144000 ms) Nov 10 18:16:54 NOTICE[1089948224]: chan_sip.c:4023 sip_reregister: -- Re-registration for [EMAIL PROTECTED] So it may be a good patch for * behind nat, not so good for * on the public net ?
