Hi,

Have you also configured your DSP's for other things like transcoding / conferencing / mtp?

Are all the outbound calls definitely G711?

What gateway is it?

Cheers,

Tim

Guys,

I need some advice. I have a customer with Multiple(about 5 and growing) SRST sites hanging of CallManager 6.x. They have WAN connectivity via ADSL, and a BRI port for redundancy. They then have 4 x 2 port BRI cards for Voice. I have a PVDM2-32 in each gateway. I cannot get more than 4 calls to the PSTN on any one site. 5th call gives me the following error: "Cause i = 0x80AF - Resource unavailable, unspecified"

Any ideas?
