Hi everybody, I intend to use Freeswitch with two Ekiga Softphones. SIP Instant messaging works between the two softphones but SIP presence signaling is not managed by the softphones. I try to use other softphones (QuteCom and SIPCommunicator) and it is the same. I have the following error in my FreeSwitch console: [WARNING] sofia.c:75 sofia_handle_sip_r_notify() delete subscriptions for failed notify Is there any special configuration for SIP instant messaging presence? Thanks. G.C. Hi everybody, I intend to use Freeswitch with two Ekiga Softphones. SIP Instant messaging works between the two softphones but SIP presence signaling is not managed by the softphones.
