| 15 | 8 | Adrian Georgescu | This provider requires a public IP address in the Contact header. This is plain wrong as explained [[MostEncounteredProblems#SIP-Provider-requires-STUN|here]]. Blink does not work for this reason on 1&1 network. |

| 19 | 7 | Adrian Georgescu | There are reports that Blink does work with Mitel equipment yet nobody has provided a SIP trace or logs of such failure. We had not find such hardware to test with but rumor has it the reason is the fact that Mitel sends INVITE with no SDP considering everything is a audio call. Blink as a multimedia client need to know what type of media is proposed in order to start a session. We did a synthetic test and hack to handle this in Blink, but nobody could confirm it works. |
