interconnecting oxo with panasonic by sip user

[kapil_elvis]

We are interconnecting oxo with panasonic NS 300
Panasonic engineer creates SIP extension with authentication in his system, and told me to configure it in oxo.

Please tell me can we do this to interconnect both systems.

thanks

Yes you can, but try to do this using SIP trunking.

Dear experts,

Hope you will be able to help me in solving this requirement

We have the following scenario.

Site A
1. Panasonic KX TDA 100D Digital PABX
2. 10 x Extensions
3. 3 x Analog trunks ( provision is present to add more analog lines )

Site B
1. OmniPCX Office RCE Medium
2. 10 x IP Extensions
3. 2 x Analog trunks.

Site A and Site B are connected via Fast VPN.

I want People from Site A to Call Site B and vice versa ,

I have planned to add few SIP licenses to the Alcatel and keep the PAP devices connected to Panasonic. but is it possible to configure 2 way connections?

What is the best practice to follow, What are the things I will need to buy ?

Please advise
