Voice Drop

Post by mohdaliy » 11 Oct 2013 04:16

Hi expert,

I would like to give 1 question, our PABX system OMniPCX, R9.1 and CPU 7_2 got problem when call inter building. we have 4 building with 3500 user using remote shelf, each remote shelf have INTIP 3. The problem is when some one call from building A to building B, building B have a ringging but when they pick up the call automatic the line no voice.

We already do Network Link Assessment test but all network for voice, it looked good.

Can you help me.

Post traces for your calls.
Do you have same codec configured on both sides?

Check network settings (LAN). For ringing - you need IP flow CPU-INTIP 3 (building B), for voice - INTIP3 (building A)-INTIP3 (building B).

Main problems:
- NAT used;
- not allowed RTP trafic INTIP3A - INTIP3B;
- not managed (or wrong management) Ethernet parameters for INTIPA (shelf/ board/ ethernet parameters) - GW, mask...
