small office trunking advice needed

[nitz01]

hey all,
here is the delimmna. we have three offices interconnected using SCN/H323 between a 406v1 and two small offices. all are running 3.0. one of the small office installation has outgrown the 4 analogue trunks, and i find it hard to pay U$3K for T1/PRI card and associated line expenses. is there a reliable and tested solution to add more line trunks via H323 or SIP? can anyone point me to a reliable resource, avaya reseller and h323/sip provider with experience in this area. a concern with SIP would be that the 406v1 could not be upgraded to a matching 4.0 version and SCN between offices may be affected. Thanks for your help

It's not possible to upgrade the 406V1 to 4.1(9) to do SIP but you could use AudioCodes to realise this, they have the units in BRI, Analog trunk an PRI/T1 versions.
AudioCodes can do SIP and H323 both work great.


Greetzzz...Bas

Is this site likely to gow much more??? Is it worth looking at moving upto an IP500 for that site. Plenty of room for expansion.

I'm sure you could replace the whole thing for less than the $3K for upgrading the SOE to T1.

Whitout doing the Maths, less than $2K to add a couple more alogs and get a new kit.

thanks for the replies, but i really wish people would take the time to read.
bas1234 i am not trying to upgrade the 406v1 to 4.0/1. i am considering doing so on the small office, but my concern was interoperability running the small office on 4.0/1 while the 406v1 is on 3.0 since they are connected by h323 trunks and SCN.
jamie77 the office is not likely to grow to much more than 10, but it is a sales office so calls are constantly being made. the small office can meet the need, i just need more trunks on it.

is there anyone out there doing successful h323 trunking or SIP trunking with reliable providers on the small office?

Avaya has always said that releases will be fine with SCN as long as they are not more the one major difference between them. Example 4.0.x is fine with 3.2.x.

good to here that kurt. in any event, would it be possible to buy a 406v2 control unit, switch over the PRI 24 T1, ATM4, and VCM5 cards from the 406v1 and have it work with the existing DS30, 2xDS16, POT16 expansion modules. this way everyone can be blissfully happy on 4.0/1.

i'm still hoping someone can recommend a good 3rd party SIP/H323 trunk provider???

 

[jamie77]

The expansion modules and cards you list are compatible with 4.0/4.1, just replace the 406.

Never used H323 for trunks from a provider. Only PBX to PBX.

To use SIP you will have to upgrade the SOE to 4.0>. To use SIP on 3.0 you will need a SIP gateway which will require trunk connections to your SOE, which you are short of!!!!!

Nitz01 whats your locale?

http://www.12connect.com

is maybe a good provider.

You can have almost every country number in your home country. Good support but they have to make a special change for Avaya SIP because the avaya can only have one IP adress of the ITSP so they route more numbers to one account name/number.

Jamie77,

He could break out on the 4.0 with sip via SCN.

bas,
i'm in the US. the majority of the calls with be within the US as well, so i'm more interested in reliable nationwide calling than inexpensive international rates. if i could get both that always a plus.

so far it's looking like investing in the 406v2, swapping over cards from 406v1 and reconfiguring at the central site (miami). upgrading 406v2 and 2 small offices (newyork and italy) to 4.0, then hack away at sip trunking in newyork to provide extra lines needed.

thanks again bas. one more question for now. we've never used the wan/firewall/vpn features of our ip offices, as we have either checkpoint or watchgaurd firewalls in place with site to site vpn's. will this be an issue with sip trunking, or will the ip office play nice with our firewalls when configured correctly?

 

[Bas1234]

You can also use the Lan port for sip, but it's best to use the Wan port. Turn the firewall on if the wan port is connected with-out a firewall to internet. Your IPO needs to have acces for sip thru the checkpoint.

Here you find a lot of info. Some providers need different settings then others.

NITZ,
Thanks for your request for FREE technical support because you do not have time, or do not see the value of hiring one of the guys that you are willing to take FREE help from, and then complain about them not taking enough of their own FREE time to properly read your post.

bas is a skilled, and experienced professional, as well as generaly courteous which it seems at least one of the three of those is something you are not. I am suprised that he still helped you even after your rude treatment of the technician that you hired, oh wait, you didn't hire him.

I realize that you are possibly as highly skilled, and even helpful person who contributes to the well of free support in your areas of expertise to the point where you should feel entitiled to scolding people who are returning your openess to help others from your profile.

Maybe an apology, and getting off your high horse would be advised. If you are looking for a local tech google Sundance it can help you find one, and is in my opinion the best polace to find good local techs.
