Does anyone know the parameters to configure Vonage as the generic sip trunk provider on a UC520?
I have attempted several times to request this info from their tech support but they claim they dont share this info??? The last conversation I was told the proxy and DNS server targets are constantly changing but they would give me the current state. I have tried this but it seems the calls dont complete since they cannot authenticate to their sip proxy.
It does seem odd since both Cisco and Vonage claim to be good working partners in the Sip arena yet they (vonage) arent interested in sharing this info and dont know anything about the UC500 SBCS platform while Cisco does not include this provider in the Sip choices. Is there a future plan to include in the xml script?
Typically we have seen folks connect the UC500 to Vonage using FXO ports as below:
UC500 -- FXO -- FXS -- Vonage ATA -- SIP --- Vonage
They are leary of allowing SIP configuration to be done outside of devices they control and while we do work with them on various different areas (ATAs and the SIP core network) - SIP trunk settings directly on the UC500 is not in the plans. If you do have the settings I can generate an XML file for you (https://www.myciscocommunity.com/thread/7262?tstart=0 has info required for this) but no guarantees this would work given the way the Vonage network is setup (as its more consumer oriented than business SIP trunking).
