Telephony Card with FreeSWITCH- Troubleshooting
- Nathaniel Halbrooks
Important Note Regarding FreeSwitch® and FreeTDM® Support
Support for FreeSwitch and FreeTDM for Sangoma telephony card products are no longer provided by Sangoma. All FreeSwitch drivers and applications are provided as-is with no warranty.
Sangoma was previously involved in the FreeTDM and FreeSwitch projects, but has refocused its development efforts primarily on Asterisk-based platforms including FreePBX. The information on this page and other FreeSwitch- and FreeTDB-related pages on the Sangoma Wiki has been retained for historical and reference purposes, but should not be relied upon as reflecting Sangoma's current development efforts or support policies.

Layer 1 Statistics
The layer 1 statistics command will print layer 1 statistics as reported by the Wanpipe drivers.
Usage: l1_stats <span name>
Freeswitch example: ftdm sangoma_isdn l1_stats wp1
Protocol Status
The protocol status command will print the signalling status of each span. All ISDN PRI spans and all ISDN BRI Point-to-point spans need to have their signalling status "UP" before attempting to make calls. On ISDN BRI Point-to-multipoint spans, the signalling link may be in "DOWN" state even though there are no line problems.

Freeswitch example: ftdm sangoma_isdn show_spans
