SRP527W SIP source IP registration

[n.brote]

Hello,

We have a SRP527W, we have created VLAN for DATA and VOICE remotly connected to an office by VPN.

VPN is working fine.

Now we want to register SIP lines integrated in SRP527W to a Cisco Call Manager located in our office.

The problem is that the source of SIP packets is WAN interface of the SRP527W, so packet wont pass in the VPN. Is possible to change the IP source of the SIP registration ? The most useful will be to set the IP source SIP on the voice VLAN.

Thank for your help!!

Hi Loic,

Unfortunately this is not possible.

(The reason why the voice stack is bound to the WAN interface is based on the product's initial design as a service provider gateway.)

Hello,

Thank you Andy for your answer, I have foud a solution :

Make an IPSEC VPN between WAN IP interface and remote office LAN in the SRP527W.

So packets from WAN and to destination of office LAN are routed in the VPN.

It's work, but not really "clean". It can be used for waiting a new firmware that can be change that.

Loic
