I have SIP Phone Plugin installed openfire 3.5.1 and SIP Softphone Plugin installed in Spark 2.5.8. In Spark, it won’t registered. When I go to openfire, click on Phone, it says “RegisteredFailed”. I have installed Asterisk-IM Plugin in openfire and have it setup and working. But for SIP Phone Plugin, it is not working. Both plugins, asterisk-im and sip phone have the same concept where connect plugin to asterisk server.
Do you have any issues with the voice quality? Does it work well for you using SIP Phone Plugin. We have some issues and I would appreciate if you can share some information.
