First post - hope it is in the right place.
I have a bunch of 7962G’s that I am attempting to deploy.
I have FreePBX with Asterisk 13.29.0 - patched with the call manager patches.
I have all the phones configured and working, with two lines, so I can enable paging.
The loads file is SIP42.9-4-2SR3-1S
This all works. (Auto answer works perfectly)
When I enable the BLF extensions on the server; from this page (I have a 7915 sidecar configured)
The phones stop attempting to register the second SIP line; and hence the paging functionality is not available.
I have been banging my head against a wall for about 2 days now.
Happy to post any config files, but the moment I add the cisco_usecallmanager=yes in sip_custom_post.conf my second line functionality stops working.
Has anyone seen anything like this? Where should I look next?
I’ve tried tweaking the confs - both the SEPMAC and the sip[*}.conf and I have narrowed it down to that one line.
tcpdump shows a little information, but I am not sure how to understand it. There is nothing obvious (going back to the phone) between a handshake with the cisco_usecallmanager=yes and no cisco_usecallmanager prior to the second register call from the phone.
I use [tcpdump -nqtttvv -s 0 -A “src host x.x.x.x and dst port 5160”
Any help is appreciated.
