Hello all,
I currently am running a small BCM50 system with RLS 5.0 with 3 1140E phones, 2 I2004 phones and 2 digital T series sets. I have 2 analog trunks, which seem pretty backwards to be using these on a system with IP telephones.
I have set up SIP service with an external carrier called nexvortex.com and it works seamlessly wonderful with the digital sets. Unfortunately, the IP phones are another story. On my 1140E phones I cannot place any calls out, I receive a fast busy after 8 seconds. The external SIP carrier is telling me that my BCM/BSR222 keeps sending a signal saying that it needs to "re-invite" the session and thus no calls can get through. I can receive calls and CID, but when I answer the call, the line immediately hangs up and the external SIP carrier calls this a "Internal Server Error" If I try to park a call from the digital phones and then retrieve on an IP phone, an error 500 occurs again from the SIP provider called another "Internal Server Error." It seems as though something on my BSR222 is preventing me from making and receiving calls. I have set up the port forwarding to allow port 5060 to 5080 be an exception to the firewall.
Secondly, when I try to place and receive calls to the I2004 phones, the somewhat same conditions occur but with a few variations. I can pick up a parked call on the phone, but I hear no audio on the I2004 end, but I can hear audio, say on my cell phone when I try making the call. So it's a one way conversation. I talked to a friend at Nortel and he traced my route and said the problem is that the phone call is only getting to the BSR222 as far as 192.168.1.2, the BCM's address and not the 192.168.1.8, the IP I2004 phone itself! So far, he said the best thing to do for now is use the digital phones and wait for BCM 6.0 to come out. I am kind of hoping a patch comes out before then. How do we push Nortel/Avaya for a patch?
Has anyone been successful of using the 1140E IP phones with external SIP carriers and a BCM50 RLS 5.0/BSR222, or am I a pioneer and first to do this?
What a frustrating experience this has been! I've been trying since January and finally was able to get the Digital phones to work on it. The digital phones are ok....but I want to use my expensive 1140E phones with all the bells and whistles! I want to be able to park a call on one phone and not have it hang up on me when I go to pick it up on the IP phone. To my knowledge most Nortel experts say I have been one of the first people to actually use an external SIP provider on the BCM. I originally had a 3.0 system and just spent money out of my own pocket to upgrade to 5.0 to correct the IP problems....well apparently there seems to still be a lot of bugs here. I am doing this for the love of telecom and as an interest of mine, more of a hobby.
Can anyone help? Why is it so hard to use IP phones on VOIP SIP trunks?? It seems so backwards for me to be using the analog trunks for the IP phones and the SIP trunks for the digital phones.
Thank you.
