I've tried multiple times to call our Cisco SX10 videoconferencing endpoint whose SIP address is address@hidden
from Linphone, but Linphone doesn't seem to discover Cisco's SIP servers via DNS SRV. The Linphone log shows an error message
I have no trouble calling from the SX10 to my SIP address using Linphone.
Is Linphone, using a SIP address at sip.linphone.org
, able to discover Cisco's SIP servers? Or might there be something else wrong?
