Cannot get as5300 accept modem call

Hello All!

Brand new AS535-2E1-60AC purchased a week ago. Were trying to get it to accept modem calls - no way! After the number is dialed immediately got a

busy signal. Tried multiple configurations until ended up with clearing it up all and carefully copying line by line the example configuration from "Configuring an AS5350/AS5400 for Incoming Async and ISDN Calls"

only substituting lines pertained to T1 with ISDN PRI QSIG

No success! Debug output shows:

However, if we add dial-peers in order to treat the call as voice everything is ok. The call is being started, progressed and completed successfully.

So the voice proccesing is perfect.

Does anyone happen to encounter this sort of a problem?

Would appreciate any help!


Re: Cannot get as5300 accept modem call

Check whether its a Qual DSPM module. If so it cannot be used only for voice and Analaog call cannot be configured.
