Unified Communications
Hi guys, currently the client have 2 SIP line and a hot-standby set up for the IPPBX. So SIP 01 will connect to IPPBX 01 and SIP 02 will connect to IPPBX 02. My concern here is, how do I go about doing the configuration for these 2 SIP in a hot-standby set up ? I understand that I need to configure everything in the virtual IP, and the secondary IPPBX will copy all the inform/changes made in the virtual IP. How do I key in two different SIP line information into the hot-standby setup?

Eric Jiang Hi redjoker, Yes, the configuration will sync between the primary and secondary server. are they normal register sip trunks or dedicated peer trunks from the provider?
You can just register the two trunks on the primary server and select both of them to the outbound route the PBX will always use the first available trunk for outbound calls and when the secondary takes over it will do the same.

redjoker Hi Eric, thanks for the respond, it's a dedicated register trunk. I thought that SIP01 is directly connect to WAN port of Primary server, and SIP02 directly connect to WAN port of Secondary server, so the idea would be, when primary server down, secondary will take over. Only the WAN port configuration of the server have different configuration. Can I do this in this HA yeastar environment or I am wrong? Please advice.

Eric Jiang Hi redjoker, you only need one sip trunk. We have a feature called 'Enable unilateral WAN Port' in hot standby which will disable the WAN port in the secondary PBX and enable the WAN port when it takes over(become the primary).
What you need to do is to connect one line to a switch then split to connect to the WAN port of each PBX.

redjoker Hi Eric, thank you for the solution, so in this scenario, I would need to tell my ISP to combine the two SIP line to become one then we can use the solution you have put out. How about if I have two PRI E1 line come in? Can I plug in PRI E1-01 to primary and PRI E1-02 to secondary server? Will the trunk redundancy happen if primary server is down?

Eric Jiang Hi redjoker, the secondary will sync the configurations like DOD settings from the primary server, cam the PRI E1-02 use the same settings?

redjoker Hi Eric, when in redundancy, PRI line in primary server is up, the secondary will sync any configuration made in the Virtual IP but PRI line in secondary server not up. However, when Primary server is down, secondary will become the active server, then the PRI line in secondary will be up, continuing calls traffic. This is the set up we currently have.
Another question regarding the SIP line, the client is adamant wanting to use two SIP trunk. Reason being is because they want redundancy for SIP trunk. However, from your solution, I can only use 1 SIP line. They are worried that if that 1 SIP trunk is down, at least they have another SIP trunk to act as a failover trunk. However, I cannot register both SIP trunk into the Yeastar Hot Standby environment. Any other solution for Yeastar S-series to accept two SIP line coming in into yeastar Hot Standby?

Eric Jiang Hi redjoker, You can register two sip trunks at the same time and add both trunks to one outbound route, the PBX will always use the first available trunk to make the outbound calls.

redjoker Hi Eric, yes, I can register two sip trunk account at the same time, however, my ITSP and customer wanted the two physical SIP trunk line to be connected to each of the PABX. I did register two SIP trunk account at the same time, but the ITSP told me that do not do that as it will impact the service. Based on the SIP trunk information they gave me, both SIP trunk are pointing to same SIP server and media IP address of the ITSP.
