    SBC with two PBX

    s_t New Member

      I have two local PBX from different vendors. They each have a different number of configured extensions, but will be using the same SIP provider. Can you use the SIP trunk failover to try each PBX for a registered user? For example it tries the PBX 1 for telephone number 555-1212. However it only exists in PBX 2.  Could you set it up so it would fail on PBX 1 and then try PBX 2? I read the documentation on "Configuring SIP Trunk Failover in AOS". The scenario in the document refers to two separate SIP providers/ISPs. Would the similar work for separate PBX systems?

          Could I route the call based on the invite message to the particular PBX? Example: If it's this phone number/sip address it goes to PBX 1, if it is the other it goes to PBX 2. PBX 1 has about 100 phones on it, PBX 2 only 20.

              Yes, see example I posted. Bundle the numbers to each grouped-trunk accordingly. You can save some typing with wildcards in the number patterns.

              Yes. Use the cost metric on the voice grouped-trunk configuration for each PBX.

               

              For example, if 555-0111 is primary on PBX1 and 555-0122 is primary on PBX2.

               

              !

              voice grouped-trunk PBX1

                description "SIP to PBX1"

                trunk T01

                accept 555-0111 cost 0

                accept 555-0122 cost 100

              !

              voice grouped-trunk PBX2

                description "SIP to PBX2"

                trunk T02

                accept 555-0111  cost 100

                accept 555-0122 cost 0

               

              When a call comes in for 555-0111 it will send an INVITE out trunk T01. If no response or rejected then it will try T02, and the opposite for 555-0122.
