Always fun integrating with proprietary pbx's... is there a way that is "generally accepted" as handling hold invites from devices such as Mitel or Toshiba?
We're not proxying the media, so these devices are trying to send an Invite to the endpoint when calls are placed on hold.
I feel your pain, I'm struggling with a similar problem. And in my case the problem is Asstra/Mitel it they barf on a received param as quotedstring (which is rfc3261 compliant) with a "400 Missing, Erroneous or Multiple Contact header field(s)". Removing the quotes fixes this, but isn't rfc compliant and thus failes on many other devices....
