I am unable to get any configuration parameters to work on my SRP547 for VOIP. ADSL2 works fine. Equipment replaces a ya.com (Arcadyan ARV4518PW) which worked ine albeit with significantly less features. Problems encountered due to the lack of equivalents for some parameters and an overabundance in the new unit which simply don't exist in the Arcadyan product.
The only items listed in the current equipment configuration are:
X = ID'ed in CRP547
User ID: X
Display Name: X
Use Auth ID: X
Auth ID: X
SIP Domain: ????
Listen Port: assume SIP Port
Listen VC: ???
Proxy Server: X
Proxy Port: X
Use Outbound Proxy: X
Ourbound Proxy Port: X
Registar Expire: X
DTMF Mode Outband (RFC 2833) - can't find equivalent
DNS SRV: X
Registratuin Query: X
Available Codecs: X
I don't know if just identifying the above is sufficient to make it work or does the service provider need to supply more parameters.
I'd be surprised if it were not possible to get your service registered and working with the SRP540. I suggest that you open a case with the Small Business Support Center who will be able to help you further. See the following link for more details:
You should check that DNS is configured on your SRP (to ensure that the proxy address is being resolved correctly).
Beyond that, the packet capture diagnostic and/or system logging can be used to diagnose the reason why this is not working further.
By the way - as I mentioned before, RFC2833 DTMF is referred to as AVT in the configuration interface. This is enabled by default, so should be used automatically if required by your service.
