3662; vofr, T1, dial = "no resource avaialable"

have a 3663 (co), that goes to (36) stores, we have 1760-V in each location, one location has been up and running for over (1) year... all of a sudden we can not use (4) digit; inter-corporate dialing.. fast busy after dialing (4) digit extension... same at location or from the (co)...

3662_HQ#sh interface Serial1/0.25

Serial1/0.25 is up, line protocol is up

Hardware is DSCC4 with integrated T1 CSU/DSU

any ideas where to look? have had at&t test circuit, all good, we can transmit data fine, just not voice?

Re: 3662; vofr, T1, dial = "no resource avaialable"

Hello Al,

this is what the Output Interpreter says, you might want to try and enable DTMF-RELAY on your dial peer and see if that changes anything:

'dtmf-relay' is disabled on this dial-peer. When dtmf-relay is enabled, the DSP generates Annex A frames instead of passing a DTMF tone through the network as a voice sample. It is recommended that this command be used with low bit-rate CODECs (around 8000bps or less). To enable the generation of Annex A frames for a dial peer, use the 'dtmf-relay' command.

Georg thanks for the input, (1) question though, how come the rest (30) of my locations work with this disabled?

Re: 3662; vofr, T1, dial = "no resource avaialable"

also, you mentioned that it was for LOW codec complexity, 8000 or below;

in my config, i show:

voice-card 2

codec complexity high
