We have been running a remote office 9150 over our VPN over the internet to an RLC in our main office for a little over a year now. The 9150 and RLC are both on software revision 1.3.4. Our IT department knows very little about the system and all the config changes in the system are done by an outside company. We are stuck in a lease with no control over who maintains the system, and we have pretty much lost confidence in the maintainers ability to configure this system. I am just a tech/geek user on the 9150 end that is trying to figure out how to make this thing useable (with the cooperation of the IT department).
At this point I would say that running over the internet is probably a bad idea. We often have poor audio quality and lots of dropped syllables. For now this is what we are stuck with so I am trying to make the best of it. If anyone else has done this successfully and can offer suggestions to get it to perform better I would love to hear them. We already have the Jitter buffer at the maximum 90ms... Is there any way to increase it further?
I currently can only access the 9150 and RLC configurations, so I am blind to what is on the PBX side. Can anyone clue me in as to how the 9150 ports get matched up with PBX (Meridian-1) extensions? For instance, my phone is on 9150 port 9 configured as Local & Remote with a DN of 5078 and which points to RLC port 9. RLC port 9 is configured as Remote and usage is Dedicated. My extension in the PBX is 8078. Is there something on the PBX side that points to RLC port 9 and says it is 8078, or does something translate the 5078 to 8078? Th PBX extension seems to override the local one as my local line appearance key shows L8078 and I can not even dial myself locally with 5078... only 8078 (and my alternate PBX extension of 4078) work. What links up the 9150/RLC config with the PBX?
Currently our bridge port configuration does not seem to be working. When we try to transfer a call from the local BRI lines to a PBX extension it does not work. We have two bridge ports defined as Remote on 9150 ports 46 and 47 (with matching port numbers on the RLC). DNs are 4046 and 4047, phone type M3903, Bridge port enabled, no local call keys. No phones are plugged in to those ports. On the RLC side they are configured as Dedicated. What kind of configuration does the PBX need to match up with this? They also have G711 compression on these ports... is that necessary? Can't we use the lower-bandwidth G729?
One last question... when we loose our IP connection our failover to the BRI lines is not working. We have the first B channel defined as remote only and using 1010222 for long distance access. The RLC is also using 1010222 for LD. It did work at one point, but now it has stopped. When it dials there is a warning in the RLC log about possibly running over a voice connection. I tried taking out the 1010222 code just to see if it would work and it still reported problems initializing the connection. Does anyone have any hints on how to get the proper long distance service set up to carry a 64k data call? Any ideas how to debug why the connection is not working?
I know I have asked a bunch here... I'll be happy for any little tidbits of information or pointers to documentation that anyone can offer. I have the 9150 and RLC documentation available (and have spent alot of time pouring through it all). I don't currently have any Meridian docs.
Thanks in advance!
