I am seeing my phones continuously sending a:
SUBSCRIBE sip:1@:5061 SIP/2.0
These phones have registered correctly with their assigned extensions and everything appears to working fine, but their is some heavy log spam from these continuous attempts:
res_pjsip_mwi.c:713 mwi_new_subscribe: Unable to locate aor 1. MWI subscription failed.
Turning on the pjsip logging I see the subscribe events in question:
<— Received SIP request (609 bytes) from UDP:<phone_ip>:5060 —>
SUBSCRIBE sip:1@<server_ip>:5061 SIP/2.0
Via: SIP/2.0/UDP <phone_ip>:5060;branch=z9hG4bK1ea9db48730F09B3
From: “Extension 2005” <sip:2005@<server_ip>:5061>;tag=C363B6D2-1C8418FD
CSeq: 1 SUBSCRIBE
Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, INFO, MESSAGE, SUBSCRIBE, NOTIFY, PRACK, UPDATE, REFER
I don’t have an extension or ring group “1” and am curious why my phone are trying to contact this address.
Has anyone seen this behavior?
