[Asterisk-Users] Cisco As5xxxx audio issues

[Brian S. Adelson]

Is anyone aware of any issues when using a Cisco As5300 to deliver
inbound SIP calls.  I see the call coming into the Asterisk unit, but
I do not hear any audio.  This is a intermittant problem as sometimes
does does work and no modifications are being made.

Below is my configuration for the Cisco As5xxxx

dial-peer voice 25 pots
 incoming called-number 877.......
 direct-inward-dial
!
dial-peer voice 2627 voip
 destination-pattern 877.......
 session protocol sipv2
 session target ipv4:XXX.XXX.XXX.XXX:5060
 session transport udp
 dtmf-relay rtp-nte
 codec g711ulaw

Thanks in advance,
