I’ve installed a PBX in a Call Center which consists of:
- Asterisk 1.4
- 2 Audiocodes MP-118 (8 FXO ports each)
- 2 Audiocodes MP-124 (24 FXS ports each)
- Some Polycom and Linksys IP phones
On certain occasions the following situation takes place:
A: someone who phones the Call Center from a PSTN number and is placed on HOLD by a member of the staff.
B: somebody who tries to make a phone call from inside the Call Center to another number of the PSTN, when every PSTN line connected to the FXO ports is in use (busy).
B gets automatically (and surprisingly) connected to A.
I cannot give you any further details besides the fact that an average of 5000 calls a day are made in this scenario and the problem described above was reported only a few times.
Any idea of what might be happening?
Thanks in advance!
