1. Is there any way or parameter setting to speed up call routing to
PSTN line ? When number is dialed on phone connected to FXS
and routed via FXO there more then 5 seconds need to receive
ring-back from outside public PBX.
We tried adjust Interdigit Long Timer: to 1 and Interdigit Short Timer: 1
result is the same. Is there any other parameter which can be adjusted to
speed up this dialing.
2. One question about firmware ?
Current firmware is
Cisco SPA8800 IP Telephony Gateway with 4 FXS and 4 FXO Ports
Voice Gateway Firmware-6.1.7
there also exist
Cisco SPA8800 IP Telephony Gateway with 4 FXS and 4 FXO Ports
Analog Telephone Adaptor (ATA) Firmware-6.1.11
Can someone from Cisco explain what is difference and can both of them used on same device or not ?
3. Voice quality on that device definitly is not on Cisco standards.
