I am trying to configure TDMoE between two servers without E1/T1 hardware installed. Without dahdi_dummy all running well but with very bad sound quality(no synchronisation source).
When trying to run dahdi_cfg with dahdi_dummy loaded, i receive a message:
DAHDI_CHANCONFIG failed on channel 31: Invalid argument (22)
Selected signaling not supported
Signaling is being assigned to channel 16 of an E1 CAS span
So channel 31 is left unconfigured and doesn’t work, but if i make number of channels 32 or more, or add more dynamic spans, i can ignore this problem as i am using only first span with channels 1-31.
But i like to know if this problem can be solved in a more civilised way. Maybe i am missing something in config files ?
DAHDI Version: 2.11.1
CentOS release 6.3 (Final), Linux node1 2.6.32-279.el6.x86_64
