Hello All,

As there is no command line option provided with 'sangoma_isdn' library for restarting a single PRI line, we have made some custom changes in 'ftmod_sangoma_isdn.c' in order to achieve that.
To summarize the changes: It adds a new command line "ftmod sangoma_isdn restart_span" which calls ftdm_sangoma_isdn_stop1( ) and then ftdm_sangoma_isdn_start() to restart the given PRI line.

ftdm_sangoma_isdn_start() was already present in 'ftmod_sangoma_isdn.c' and ftdm_sangoma_isdn_stop1() is a modified version of ftdm_sangoma_isdn_stop().
You can take a look at the code snippet here:

The changes have been tested extensively and working fine as of now.
Please let me know if you see any potential negative impact of this fix in FreeSwitch.

Thanks
Deepika

Hello Guys,

I am facing a problem with some of the PRI lines on my FreeSwitch machine (Version 1.2)  and I want to restart those selected PRI lines in case they get stuck.
But I didn't see any option for restarting a particular PRI line with sangoma isdn.
freeswitch@internal> ftdm sangoma_isdn
Usage:
    ftdm sangoma_isdn trace <q921|q931> <span name>
    ftdm sangoma_isdn l1_stats <span name>
    ftdm sangoma_isdn show_spans [<span name>]

However, If I use libpri for signalling, it does provide an option of restarting a particular PRI line :
freeswitch@internal> ftdm libpri
Usage:
libpri kill <span>
libpri reset <span>
libpri restart <span> <channel/all>

I'm wondering if this support has been provided with sangoma_isdn or if I'm missing something here. Please suggest if there are any workarounds to achieve this with sangoma_isdn.

Thanks
Deepika
