Hi,

I am configuring the CISCO2901/K9:

Cisco CISCO2901/K9 (revision 1.0) with 483328K/40960K bytes of memory.

Processor board ID FGL1737248D

2 Gigabit Ethernet interfaces

1 terminal line

4 Voice FXO interfaces

DRAM configuration is 64 bits wide with parity enabled.

255K bytes of non-volatile configuration memory.

250880K bytes of ATA System CompactFlash 0 (Read/Write)


After I finish FXO configuration and make phone calls from SIP phone CP-3905 to PSTN through FXO ports. The problem is while 02 parties are talking about 2 to 3 minutes, and the call is disconnect suddenly.


Attached file is my running configuration. How can I fix this problem?
