[asterisk-ss7] Problem with Asterisk SS7 MTP2 timer

[Facundo Ameal]

Hi Mark! I had the same issue. Please check the timing source in
zaptel.conf and then do the following:

1) Stop Asterisk
2) Unload Zaptel modules
3) Load Zaptel modules
4) Start Asterisk

That solved it for me.


Hope it helps.

Best,
