I'm having a weird problem with faxing using the 2921 series router with a 4 port FXS card. This is a new site install in South Africa .You can succesfully make the outbound call from the FXS port and the other end will answer and the intial conenction works, as soon as the transfer starts the call drops:
Here is the config from the router:
no ip address
isdn switch-type primary-net5
isdn incoming-voice voice
no cdp enable
dial-peer voice 210 pots
dial-peer voice 201 pots
Any suggestions as to why it is dropping?
Thanks in advance
It's easier to test the configuration workaround than to upgrade. Especially since the user likely does not need Cisco Fax Relay to begin with. But, as you wish:
I've got a 3925 with 151-2.T2 and had the same issue. Couldn;t do a bug lookup on that ID but the work around resolved my issue. I also had out of DSP resources but had plenty on the router.
I think I'm having same issue one router 2921 but with BRI's connected to PSTN instead of E1. Some of the BRI's are one the EVM module where FXS ports are and others BRI's are in VIC2-2BRI -NT/TE.
No local-bypass command is realy necessary?
with these router commands i will have to config fax machine speed to 14400 ?
You are getting no circut /channel not availabnle error that mean you dont have channel for this call (this could be pyscial or itsp problem) Please reach out the your itsp should check their end. Its not related media resource issue.
