| My debug isdn q931 started showing me sending disconnections due to
'resources not available" when I call from my 7960 phone to PSTN. I
have a 2811 with 2 PRIs to PSTN and 300 7940 phones.
It started after I wanted to add 60 numbers on a Castelle Fax Press T1
PRI (MGCP). I added Route Patterns in CCMAdmin pointing to the Castelle
as these are mostly inbound faxes to the Castelle Fax Press.
I didn't want to add 60 individual dial peers, so I put it global. I
thought it listened to each call for fax/modem tonesand didn't invoke
any modem passthrough resources unless needed. How many modem
passthroughs can a 2811 handle?
Iunderstood since I have CCM/MGCP I must use modem passthrough versus
fax passthrough.
Voice service voip
Modem passthrough nsd codec g711ulaw
IOS 12.4.11T3 and CallManager 5.1.3-2000-2
Calls come in H323 Gateway to CallManager, then to Castelle Fax
PressMGCP gateway.I wanted to keep the Castelle Fax Press MGCP as the
administrator has no IOS experience.
