What is your IP address?
You should send calls to 78.129.221.95. If you use SIP, you MUST send calls to
our non-standard SIP port 6060. Calls to the standard SIP port will fail.
Should I use H.323 or SIP?
We support both call signalling protocols, but we recommend that you use H.323, because
it is more reliable. If you use H.323, you must enable Fast Start and H.245
tunnelling. If you use SIP, you MUST send calls to our non-standard SIP port 6060.
Calls to the standard SIP port will fail.
Does your route pass CLI?
Yes, our route supports CLI, but CLI is not enabled by default on new accounts.
If you need CLI to be enabled, please contact our support
team, who will check that you are passing is CLI in the correct format. The CLI
numbers that you send must be valid returnable numbers.
How do I send you CLI?
For H.323, you should send the CLI in the Calling Party Number element of the Q.931
setup message. For SIP, we extract the CLI from the line ID portion of the calling
URI.
What codecs do you support?
We support G.729 and G.723.1 (fast rate).
Do you support the G.711 codecs?
Our standard accounts do not support G.711. But, if you request it from our support team, it can be added. There is a 5%
uplift on rates for accounts that have G.711 enabled.
Will DTMF work?
Yes. For H.323, you need to enable H.245 tunnelling and send DTMF information in
an H.245 UserInputIndication message. For SIP, you need to send the information in
SIP INFO messages.
Will fax work?
Our service is primarily voice, but fax usually works to UK landlines. Your
equipment will need to support the T.38 fax protocol over H.323 or SIP.
Can I authenticate from a dynamic IP address?
No. You need a fixed public IP address to use 44Direct. You specify your
switch's IP address when you sign-up
for an account.
How do I add of remove an IP address on my
account?
You should send an email to our support team
detailing your requirements.
Can I have multiple IP addresses on my
account?
Yes.
Can I use a shared fixed IP address?
If you use a hosted softswitch that does not give you a unique public IP address, then
we will need to add a tech. prefix to your account. You should send an email to our support team detailing your requirements.
Bear in mind that no further per-call authentication is provided, so all calls from your
IP address and with your tech. prefix will be assigned to your account.
What dialling pattern should I use?
You should send calls in E.164 format (44 + number). Optionally, our support team can add a tech. prefix to your
account.
Do you support Asterisk?
We support Asterisk using SIP, but not IAX. But, you will need to install and
licence the G.729 or G.723.1 codec, unless you are willing to pay the 5% rates uplift
charged for adding G.711 support to your account. Also, you should disable re-invite
on the trunk group, because we do not support that feature and it is not possible to
renegotiate the media path once it has been established.
Can you configure my VoIP switch for me?
No; we do not offer that service.
