SCN ONE CALL AT A TIME?

[key4339]

I have two IP offices networked together have with 4 voice networking channels. if site A calls site B or vide versa and try to transfer back or push hold and select another intercom key and try another call the call will not go. its like I don't have enough VCM channel but there sitting there idle. when i'm monitoring the channel it doesn't even go off hook any ideas?

Replicate it with Monitor running and I bet it will give you a clue as to why the call won't go through.

Firewall with ALG turned on between the two location ??

It's only dialtone!!!

Could something silly as SCN Trunk channel set to 1 on outbound?
(Or config setup is making calls tromboning, consuming all channels)

Kind regards

Indeed, Cisco routers were renowned for causing this at one point
