I am stuck at home for 6 weeks during surgery so I hooked up 2 obihai devices (one at home, one at work) on an analog port on an intertel 5000. Works great from home, I pick up the phone, hit # and I can dial any extension or even dial an outbound number through the pbx. Incoming calls from the outside to my analog extension work great.

BUT when it's an intercom call, the device doesn't sense it as a ring since it's just 2 short beeps.

Is there any way to change the intercom ring style so that is mimics a regular ring?

I have tried changing some of the Obihai settings for low voltage short rings, but it's still not long enough.

Three station flags to try on the analog port: Different Alerting Cadence Intercom/CO Call, Different Ringback Cadence Intercom/CO Call, Extended Ring Cadence.

Press F1 and enter Station Flags in the search index for more info.

Extended Ring Cadence is what you want. Make sure yer analog station is listed under that Station Flag.

thanks guys - that did the trick.
