Dropping calls

[MTVilla]

Wondering if anyone can help.

We started small community networking with our Philadelphia office in late December. Since then, both offices have been dropping calls periodically. There is no pattern to the call dropping. It could be a callin or out, local or LD. Some people drop while others stay connected. There is no pattern.

Here is our system (all at ver 2.0 (16)):
Minneapolis
IP412 (Slot A single port PRI - not used; Slot B dual; port PRI both used one local and one LD; Wan port to Point to point connection to Philly.
2 IP430 digital stations
2 IP416 digital stations
1 IP416 Analog Trunk
1 IP408 POTS
40 phones (4424 D+) on system

Philadelphia
IP406 (Slot A not used; Slot B single port PRI; Wan port to Point to point with Minneapolis
2 IP416 Digital Stations
1 IP416 Analog Trunk
15 Phones (4424 D+) on system

Any help is appreciated.

I haven't heard of this on the new release, but with 1.4(22) I experienced this as a result of paging. If there were too many telephones in say a "page all", then the digital station module would reset. The whole system wouldn't go down, just the one or two of the expansions.

in my situation it ended up being the DS30 module with the 4424's and 4450's - I split these out between multiple digital expansions, and this remedied it.

I do not think this is an issue with 2.0, in fact I think a private build 1.4(2215) cleared this problem up, but it may be worth a try. The max number of sets in a paging group for 1.4 was 16 before 1.4(2215).
