Hello

I am using a yealink SIP-T28P and I am having trouble with incoming calls. If I reject or the caller hangs up before I get to the phone my phone continuously rings. If I answer it's fine.

Any ideas?

Any help would be great.

Thanks

Hi,
I get the same problem with a Polycom IP650. Takes nearly a minute to stop ringing after a caller hangs up. Seems other phones have a similar problem, as there is another post with the same issue with yet another make of phone (SwissVoice IP10s)...

I didn't get this with a different VoIP service so I think VoIPfone may need to add some additional signaling to improve compatibility?
