Hi there,

We are currently operating a Cisco 2600 with the following IOS:

Cisco Internetwork Operating System Software
IOS (tm) C2600 Software (C2600-IS-M), Version 12.2(15)T1, RELEASE SOFTWARE (fc1)
TAC Support: Copyright (c) 1986-2003 by cisco Systems, Inc.
Compiled Thu 27-Mar-03 16:45 by ccai
Image text-base: 0x80008098, data-base: 0x819BE084
ROM: System Bootstrap, Version 11.3(2)XA4, RELEASE SOFTWARE (fc1)
ROM: C2600 Software (C2600-I-M), Version 12.2(13)T1, RELEASE SOFTWARE (fc1)
System image file is "tftp://66.7.157.25/cisco/c2600-is-mz.122-15.T1.bin"


cisco 2610 (MPC860) processor (revision 0x203) with 59392K/6144K bytes of memory.
Processor board ID JAB033902K9 (2260688932)
M860 processor: part number 0, mask 49
Bridging software.
X.25 software, Version 3.0.0.
Primary Rate ISDN software, Version 1.1.
1 Ethernet/IEEE 802.3 interface(s)
26 Serial network interface(s)
2 Channelized T1/PRI port(s)
32K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read/Write)

Our current PSTN interconnect is via a PRI to ICG Communications.

We have had some limited success by adjusting dial peers on some connections to assist on Faxing. However to date we cannot make a modem call over this configuration.
In the past we have been able to make trouble free faxes of any size from port to port on the ADIT 600s but whenever we gate to the Cisco gateway we have difficulties.

We have no network latency issues. We have no jitter issues voice calls are clean.

We operate as follows:

Broadsoft Feature Server
SIP signaling to 2600

Cisco2600 Gateway
PRI to PSTN
SIP signaling to Broadsoft


CPE
7960 phones
ATAs
Adit 600
Cisco 2421
SIP to Broadsoft
RTP to Cisco 2600

Any help in this problem would be greatly appreciated.
