[asterisk-ss7] No audio using libss7 over E1

[David Wilson]

Thank you for your reply Kalolyan.

I've made the adjustments that you've suggested and will retest shortly.
A quick check though with regards to dahdi_monitor syntax. May I use 
dahdi_monitor as follows to show the CIC?
/dahdi_monitor 1 -v/

For monitoring channel 1.
