Is there a limit as to the amount of IP phones you can page in a group?

We have a scenario whereby we page large groups of phones e.g 20+ (5610's 5602's etc - from a 5620) and it works fine sometimes but then other times it it sounds like a mobile with extremely bad coverage or as if it's being done underwater!!!

System is 412 3.1(56) (this hasn't worked properly on any software 3.1 upwards) - it is also fully IP and layer3 switched with QoS etc.

Have checked out the VCM channel status and it appears that only 2 are being used so it's not a VCM channel max out afaik.

You can happily page 3 or 4 times fine then on the other hand it will just mess up 3 or 4 times on the trott - it's completely un-reliable and intermittant.

Cheers for any advice.
