Seeking advice re problematic DID port-in-progress
Hi, folks, After declining to sign a new 2-year $500/mo contract with my formerly-favorite inbound VOIP (DID) provider - a wholesaler based in Brussels - I'm completing the process of porting the last of my DIDs from them off to other providers with lower minimum purchase commitments. The first few dozen went smoothly, with no interruption in service (not counting the ~day of downtime that the Belgian provider put me through as part of their hardball contract negotiation tactics). However, the third-to-last DID has been in limbo for the last 3 days. Right after my new Toronto-based provider reported receiving a FOC date (25 May) for this DID, the DID in question disappeared from my control panel at the Belgian company, and calls to the DID consistently fail from various calling providers. The CDR reports at both provider control panels show no calls (neither successful nor unsuccessful) for the DID in question. When asked about this, the Belgian provider claims that they've been told by a telco (they would not name it) that the DID in question has been ported, which is (they claim) why the DID disappeared from my control panel. However, at least a dozen of the DIDs that I ported more than a month ago still show up in this control panel, even though I've confirmed repeatedly that all calls have been routing to the new provider since the port date. Additionally, my new Toronto-based provider (who have been fairly reliable) is certain that none of these calls are arriving at their network, which doesn't surprise them given the FOC of 25th May. Given these facts, and the way the Belgian provider has acted in the course of this contract negotiation, I think I'm being jerked around. The end-user of the DID in question would dearly like for their inbound calls to work again - ideally well before the 25th. I really don't want my next step to be an FCC complaint (I'm based in the US), but I'm not sure what my other options are. Any suggestions? Apologies in advance - and suggestions of better fora welcomed - if this isn't sufficiently on-topic. thanks, Graham

Re: eur.army.mil net ops contact?
There is not. The various branches we worked with wouldn't touch it unless the ticket originated internally. Once that happened, we found them to be very cooperative and helpful. Another note - each branch is separate for the most part. If you're having problems reaching the Army, Navy, National Guard, etc..., they're pretty much independent and you need to work each one separately. -- Marc Actually, there is the Defense Information Systems Agency which provides support for all branches and partners (NATO etc..). Check http://www.disa.mil/contact/ I don't know if this contact page accepts issues from outside the US MIL organization (as Marc posted), but you might give it a try. Nils Kolstein

takes precedent.
: The holdtime isn't technically negotiated, both sides convey their
: value in the open message and the lower of the two is used by both

This isn't a negotiation?
: IIRC, neither J or C reset the session with the timer change, but
the : new holdtimer expiry value doesn't take effect until then.
We use Alcatel 7750s. Damn thing just resets the session; no
warning, no nothing. :-(
: One other thing to note is that by default, keepalive intervals in

setting : holdtime to something really lower (e.g., 10 seconds) you
might want : to increase the frequency of keepalives such that the
probability of : getting one through in times of instability rise.
In particular, : congestion incurred outside of BGP, as update
messages themselves : will serve as implicit keepalives, and with the
amount of churn in BGP, : empty updates (keepalives) are rare for
most speakers with a global BGP : view.
I have been looking for info on the negative impact on a router by
increasing the keepalive frequency to a high rate. I'm sure it's
minimal for a few BGP peers, but I could imagine with a lot of peers
it's a non-zero impact.
with a keep alive interval of 10 seconds you can expect to get 10pps
from a 100 peers. the keepalive message is 19bytes
That doesn't seem particularly hurtful even by the standards of 5 year
old control plane processors.
