ISDN E1 PRI incoming calls busy out after 2nd b channel picks up

[longweb05]

I have an ISDN E1 PRI line coming in from the Telco. D Channel comes up nicely and B channels accept calls, but only the first two calls. Once two callers are online, any further incoming calls get a busy tone. ISDN Debug data reports:

**ERROR**: call_incoming: Remote Protocol Error: No b channel assigned by switch, call id 0xCE

Hardware I'm using? Cisco 2650, 12.3(7T) and NM-HDV, VWIC-2MFT-E1-DI

Anybody please help?

Problem sorted - believe it or not, it was the telco. They changed their switch setting for the line to preferrable B channel - and voila!

Thanks,

Brian
