Hi!
With the deployment of the newest firmwares for the eSeries (version 3.x) Nokia introduced STUN support for its VoIP client. Unfortunately Voxalot seems yet not to support it.
Here you can find more information on
Nokia's implementation
Quote:
Nokia S60 VoIP Release 2.0 has STUN protocol support for NAT traversal and NAT binding refresh features. The NAT/Firewall traversal features enable the VoIP functionality behind NATs of certain type.
The STUN/firewall settings cannot be edited from the terminal UI, but must be provisioned by the service provider.
If the STUN server address is not configured, the terminal tries to find one with a SIP SRV query using the Public User Identity domain of the used SIP profile.

The compliance to Noka's solution can be tested by a simple DNS query:
Code:
nslookup
set q=srv
_stun._udp.domain.tld
This query won't return any results for any voxalot domains. If you use for instance as domain.tld "sipgate.de" you will be able to see that their dns record will return an answer for the STUN Server.
Could you please add this record so that Voxalot becomes compliant to newer Nokia eSeries firmwares? Thank you very much!
