|
|
1. Brekeke Product Name and version:
2.4.8.6
2. Java version:
3. OS type and the version:
Linux
4. UA (phone), gateway or other hardware/software involved:
PhonerLite
5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :6
6. Your problem:
We have a vpn connection to SIP-Server but that connection is firewalled to allow only incoming traffic (UA -> SIP Server).
Is it possible to enable nat traversal (OPTION OK pinging) also for private address ranges? For that would keep a connection open and will permit incoming calls to UA (SIP Server -> UA).
Thanks Marco |

Yes. It will be a solution.
Tune the interval period at the [Configuration] > [SIP] -> [NAT traversal] to meet the requirement.
If the SIP server doesn't treat these UA as behind-NAT, add the following DialPlan rule.
Matching Patterns | $request = ^REGISTER
| Deploy Patterns | ®ister.contact.nat = true $continue = true
|
---------------------------
Another solution is .. set a shorter value as register period at UA settings. |
